Mechanical Test Laboratory - Wichita State University - National Institute for Aviation Research
Mechanical Test Lab

Mechanical Test Lab

Provides the highest standards in static and fatigue testing to generate material strength allowables and evaluate the endurance of materials subjected to cyclic loading.

Supports both metal and composite testing with research funded by the aviation industry and government-related research projects.

  • Impact drop testing
  • Slow-cycle fatigue testing
  • High temperature testing to 2500° F
  • ASTM/ Boeing/ SACMA standard testing
  • Ability to design and fabricate non-standard test fixtures and perform non-standard tests
  • Aging studies
  • Damage tolerance of sandwich panels
  • Specimen conditioning
  • Environmental testing (-200F to +600F)
