In accordance with ASTM E647 standard, LTI's fatigue crack growth testing generates curve displaying crack growth rate as cyclic stress intensity factor is varied. Test results also provide data points and da/dN-dK plot. Additionally, LTI can provide customers with threshold and Paris Law values. Performed at temperatures between -250 and 400°F and at loads from 50–55,000 lb, testing supports Compact Tension and Middle Tension specimen configurations in variety of sizes.
