Mechanical Properties

• Tensile/compressive/torsional (quasi-static and dynamic)
  
• Dynamic compression with confining pressures to 100,000 psi
  
• Multi-axial loading (quasi-static and fatigue)
  
• Cyclic stress-strain
  
• Stress relaxation
  
• Low cycle fatigue
  
• High cycle fatigue
  
• Thermal-mechanical fatigue
  
• Initiation and growth of microcracks
  
• Tensile/creep in hydrogen (to 3,000 psi, 1,000°)
  
• Mechanical properties from –320° to 3,000°
  

Strain-controlled low cycle fatigue tests are performed at high temperatures.

Strain-controlled low cycle fatigue tests are performed at high temperatures.

High strain rate testing to 104 per second in the split Hopkinson pressure bar, combined with confining pressures to 300 MPa, is unique to SwRI.
