Material testing can consist of performing a simple tensile or hardness test to a cyclic fatigue test. A tensile test will determine the yield strength, ultimate tensile strength, elongation and the reduction of area. A cyclic fatigue test is used to determine crack initiation and to determine fatigue life as well as to validate new materials and processes. Fracture mechanics testing consists of 3 basic tests, LCF test for crack initiation, Fatigue Crack Growth Rate da/dN test for how fast a crack will grow before becoming unstable and a Fracture Toughness test to determine the stress intensity factor before the crack becomes unstable and there is a catastrophic failure. Industries served are Aerospace, Medical Device, Oil & Gas and transportation. Understanding physical properties of materials and components provides for a more reliable and safer product.
