Material Performance Lab
M.R. Hill, MAE Department, UC Davis

Mission Statement

The Material Performance Lab enables the study of the endurance of engineering materials. The emphasis is currently focused on the study of manufacturing-process influences on fatigue and fracture and the inclusion of these influences in the design process. To this end, the lab is equipped with the following:

  • Mechanical Testing
    • Three servo-hydraulic material testing machines. These machines use state of the art digital control hardware and WindowsNT-based software to apply repetitive loading histories to test specimens. A large assortment of high-accuracy extensometers are available to measure specimen shape change with applied load.
    • Instrumentation facilities allow the use of accelerometers and strain gages to capture static and dynamic specimen response.
  • Simulation
    • Departmental computing facilities are used in conjunction with this lab to simulate testing procedures using non-linear finite element methods. Data from both experiment and simulation are compared to gain insight into failure processes.
  • Residual Stress Measurement
    • Relaxation residual stress measurements are carried out using strain gage instrumentation in combination with cutting. Material removal is perfomed using wire EDM, available in Professor Yamazaki's IMS-Mechatronics Laboratory.
    • Diffraction residual stress measurements are performed using both x-ray and neutron beams. XRD can be performed using a Scintag XDS2000 X-ray diffractometer located in the ChEMS Department. ND can be carried out at Los Alamos Neutron Science Center (LANSCE).
  • Data Acquisition and Analysis
    • PC-based hardware and software is available for digital data acquisition using LabView, as well as data reduction and analysis.
