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.
