Fatigue & Fracture Laboratory

Current Research Interest:

Computer-aided testing (CAT) of metals and  composites.
Cyclic behavior, fatigue, and fracture: testing and modeling.
Damage characterization under low- and high-cycle fatigue.
Life prediction and durability enhancement.
Stress-strain analysis of notched components.

The Fatigue & Fracture Laboratory (F&FL) at Western Michigan University is a facility for academic and industrial collaboration and interaction in applied mechanics. The AMT&E Laboratory serves as a resource for basic, applied and industrial research in the areas of material behavior, low- and high-cycle fatigue, and fracture.

MTS biaxial (axial-torsion) universal testing machine

mtsbig.jpg (28150 bytes)The MTS biaxial universal testing machine in the AMT&E Laboratory is one of a handful of such systems in Michigan. It is a hydraulically operated, computer-controlled facility capable of forces of up to 100,000 pounds and torques up to 55,000 inch-pound at frequency up to 17 Hz. This facility may perform test functions for which companies have only an occasional need. Purchase of such item by a single company would mean a large capital outlay for facility that would not be used to capacity.

MTS 810 uniaxial system with TestStar digital controller

mts810.jpg (30977 bytes)The MTS 810 TestStar Material Testing System is the-state-of-the-art  facility which  can be used to meet most  of testing needs for both monotonic and dynamic tests. The system is capable of forces of up to 22,000 pounds. The TestStar IIs software allowed for digital control and computer automation with provision to generate the standard or custom's design command signals. The hydraulically actuated grips (in both machines) ensure even specimen clamping due to symmetrical housing design and minimize any bending.

Additional equipment and capacity
Environmental chambers.
Mechanical testing of materials, parts, and structures.
