Equipment

• Two 22 kip servo-hydraulic material test systems, both with digital controllers.
• One 10 kip servo-hydraulic material test system with computer-linked analog controller.
• One 70 kip axial-torsional material test system with analog controller.

Test Capabilities

• Tensile: with axial and diametral deformation to measure true-stress and strain behavior
• Fatigue: High and Low Cycle
• Fatigue Crack Propagation
• Fracture: Brittle and ductile characterization (ASTM E399, E813, E1290, etc.)

Representative Results

• Stress-strain measurements for 17-4 stainless: waisted, large-notched, or small-notched specimen J - R curve measured for 17-4.
