Materials Testing & Modeling Laboratory

This is a fatigue testing facility that was established in 2001, in the Department of Mechanical Engineering, as a result of a DOE ERLE (Energy Related Lab Equipment) grant. The lab was established to serve educational and academic research needs as well as collaborative research and service in the area of materials testing, characterization and development of materials constitutive modeling. The lab currently contains several fatigue test cells of different capacities. The following are tests that can be run in the lab:

  1. Low Cycle Fatigue (LCF) with either Load or Strain control. Uniaxial or Biaxial (axial plus torsion loading)
  2. High Cycle Fatigue (HCF) with either Load or Strain control. Uniaxial or Biaxial (axial plus torsion loading)
  3. Thermo-Mechanical Fatigue (TMF) at temperatures up to 1100 deg-C.
  4. Crankshaft Testing

Class Use – Lab Activities

Class lab activities need to be scheduled at least 8 weeks in advance in order to ensure proper preparation of equipment for the specific lab exercises.  It is assumed that for such lab activities the faculty member and/or the teaching assistants will be the users of the equipment.  Consequently, they need to go through training.  If you have such needs, the first step would be to complete the User Application form, and follow the General Procedure outlined below.

General Procedures

  1. Discuss test needs, sample type, test type, and understand what equipment options are available for your needs with the Lab Director, Dr. Abou-Hanna (X2725).
  2. Complete a User Application form and submit it to Dr. Abou-Hanna.
  3. Discuss and schedule for training on the specific test cell for the specific test.  The trainer will be identified by the Lab Director, depending on the type of test and the equipment.
  4. Read and follow Safety Procedures
  5. Have the trainer set up and run one test.
  6. Make sure the Chiller system is turned on
  7. Make sure that the cooling system is hooked up to the pump.
  8. Follow operating procedures of the specific test equipment.
  9. Keep a log of all the calibration data on the onset of each test.
  10. Notify Dr. Abou-Hanna of the test schedule and make sure that you have another person present in the lab when you are conducting the experiment.
  11. Keep all tools and personal belongings away from test cell.
  12. DO NOT LEAVE THE TEST UNATTENDED UNTIL you are sure that the test is running smoothly, and the controller interlocks and safety features are all activated.
  13. If you are running a test, turn on the red light (coming soon) located on top of the entrance door to indicate that equipment is running and lab entry must be authorized by the Lab Director.
  14. Users need to check in and out by using the log sheet posted on the Lab door.


All students, faculty and staff while working, supervising or instructing in this room must follow these safety rules. Failure to do so will greatly increase the probability of personal injury to you or someone else. Common sense must be practiced at all times. Safety is everyone’s responsibility. Violations of these rules should be reported to Dr. Jeries Abou-Hanna, or Mr. Dave Miller.

Required Supervision

In order for students to work in Jobst 122 they must meet the following criteria:

  • For access to the lab during normal hours, students must have permission from Dr. Jeries Abou-Hanna.
  • For ‘after hours’ access to the lab, students must have additional permission from Dr. Jeries Abou-Hanna.
  • Permission to work in the lab will be granted after the student(s) have sufficient knowledge & training in working with the equipment required. 
  • Under no circumstances is a student to move, touch, operate, or similar any equipment in the lab that is not directly related to their tasks AND has received prior permission to use.
  1. NEVER WORK ALONE: Working alone while operating test machines, equipment, or handling hazardous fluids or materials is not permitted.  Students should always have someone else in the vicinity incase of an emergency.  Keep BOTH sets of doors open to hallway while working to allow access to lab incase of emergency.
  2. SAFETY GLASSES: Safety glasses or goggles must be worn while operating equipment. All persons in the area should also wear safety glasses or goggles.
  3. EAR PROTECTION: Wear ear protection when noise exceeds safe levels to safeguard against possible hearing loss.
  4. PROPER APPAREL: Before operating machinery, remove loose clothing, draw strings, gloves, neckties, RINGSWATCHES and other JEWELRY and roll up sleeves above the elbow. Remove all loose outer clothing and confine long hair. Non-slip footwear is recommended.  NO SANDLES should be worn in the lab; boots of some type are recommended.
  5. WORK AREA: Keep work area clean!!  Do not leave equipment or tools on floor in the immediate work area.  Cluttered areas and benches invite accidents. Regularly clean tools, wires, misc. bolts and nuts, dust, shop rags, etc. from work surfaces and the floor.
  6. AVOID DANGEROUS ENVIRONMENT: Do not use power tools in a damp or wet location. Keep the work area well lighted. Do not use power equipment or tools in the presence of flammable liquids or gasses.  Keep flammable liquids in safe and approved containers.
  7. HAND SAFETY: Do not put hands in between actuators and grips (the load train), or near gears, pulleys and other rotating parts on machinery and equipment. NEVER touch induction heating coils without first making sure that the power to the heater is turned OFF!  Severe injury or death may result if this warning is not heeded.  Never attempt to remove tools, specimen(s), cables, debris or anything from moving actuators or rotating parts UNTIL they have come to a complete stop. Do not wear gloves while operating machinery or equipment. Do wear gloves when handling hot materials, i.e. when you take a specimen out of a fixture that has been heated to an elevated temperature.  Do wear gloves when working with cleaners or strong chemicals which may harm skin.
  8. OBSERVE WARNINGS: Read and obey all warning and information labels, tags, decals and signs on equipment or machinery before operating.
  9. GUARDS:  Keep machine guards in place at all times when a machine is in use. Do not operate any equipment while guard is not in place.
  10. MAINTAIN EQUIPMENT: Follow instructions for lubricating and changing accessories. Inspect power cords periodically and if damaged, have repaired. Inspect extension cords periodically and replace if damaged. Inspect seals in actuators, hydraulic lines, hydraulic pumps and reservoirs, and hydraulic service manifolds regularly.  Report and clean up any leaks.  If repairs are required, report the problem to Dr. Jeries Abou-Hanna immediately.  Keep controllers, electronic equipment dry, clean and free from oil and grease.
  11. SAFE FOOTING: Maintain a balanced stance and keep your body under control at all times. Do not attempt to overreach while operating tools or equipment.
  12. DO NOT MISUSE: Do not attempt to use tools or equipment for any purpose other than that which it was designed, or to use beyond rated capacity.
  13. USE RIGHT TOOL: Do not use tool or equipment for purpose not intended.
  14. DISCONNECT POWER: Always turn power off when equipment is not in use, AS LONG AS you are the only one using that equipment.  For example, one HPU (hydraulic power unit) may supply hydraulic power to several machines.  ONLY shut it off if you are the only person using that HPU. 
  15. AVOID UNINTENTIONAL STARTING: Make sure power switch is in the off position before connecting power to equipment. Do not carry a plugged-in power tool, controller, or electronic instrument with finger on or near switch.
  16. GROUNDING: If equipment or tool is equipped with a three-prong plug it should be plugged into a three hole (grounded) electrical receptacle. In cases where an extension cord is used, make sure it also is grounded.
  17. KEEP VISITORS AWAY: No visitors are allowed in the lab unless prior approval is given.  If approval is granted, all visitors and children should be kept a safe distance from the work area and equipment (operating and non-operating equipment).
  18. CARELESS ACTS: Pay close attention to the work you are doing. Looking around, carrying on a conversation and “horseplay” are careless acts that can result in injury.  No “horseplay”.
  19. BE ALERT: Do not operate tools or equipment while under the influence of drugs, alcohol or any medication. When doing any physical work, using hand tools, power tools or other equipment you need to be alert at all times. This will prevent injury to you and others.
  20. EMERGENCY PROCEDURES: Be aware of the emergency procedures to shut down test equipment, hydraulic power units, induction heaters, and circulating chilled water if needed, even if you are not operating the equipment.  Emergency shutdown procedures will be posted on each machine.


Report any maintenance issues such as malfunctioning equipment and hydraulic fluid or water leaks to Dr. Abou-Hanna at 677-2725.  In case of an emergency, or if you cannot reach Dr. Abou-Hanna, contact Mr. Dave Miller in the Mechanical Engineering Shop at 677-2736, or call University Maintenance at 677-2915 and report the emergency.

Alterations and Upgrades

Alterations and modifications to equipment require prior approval from the Lab Director.

Lab Charges and Rates

Lab use for projects that involve external agencies will require a financial arrangement.  The rates depend on many factors, mainly test period & test type.  The Lab Director will provide the user an estimate of cost based on University sanctioned rates.  

Academic use for projects that are not funded and are not for external clients carries no charge. 

Lab Access

Use of the facilities needs to be arranged by completing a User Application form.  The user is expected to use only the equipment agreed upon in the User Application form.  If additional equipment is required, then the user needs to contact the Lab Director and request an amendment to the initial agreement.

Hours of Use

The work in the lab must be during normal hours 8:-5: to ensure the personnel are available in case of an emergency or equipment malfunction.  Special arrangements can be made if working after-hours is required, and the project faculty advisor will need to assume responsibility and be familiar with the test and the equipment and supervise the work.  Fatigue tests may go on for days at a time, and they may require frequent monitoring by users.  In such case, users should be able to enter the lab after hours ONLY to monitor and record data. 

Reporting Problems

Report problems to the Lab Director.  In case of emergency, contact Mr. Dave Miller at 677-2736 during normal hours, or University Maintenance at 677-2915.
