Mechanical Performance Group

The Mechanical Performance Group develops measurement methods, models, data, standards, and science for the mechanical properties of advanced materials (e.g., high strength steel, aluminum alloys, composites) and materials under extreme environmental and operating conditions. The Group provides expertise needed to determine materials and system performance within and outside design limits, and generates and disseminates reliable mechanical

 
The Group:
  • Generates and disseminates reliable mechanical property data;
  • Standardizes, both nationally and internationally, mechanical property test methods.
  • Performs forensic analysis of failed components and assists in investigations.

 

Group Competence

  • Mechanical testing at all size, rate and temperature scales
  • Multiaxial deformation and yield surface measurement
  • X-ray and neutron stress and microstructural measurements
  • Standard Reference Materials (SRM)
  • Hardness measurements and standards
  • Hydrogen embrittlement and stress-corrosion cracking
  • Finite-element analysis
  • Plasticity theory
  • Atomistic modeling
  • Shape memory alloys
