Fracture Mechanics and Toughness Testing

fracture-mechanics-450-1

Fracture mechanics provides great insight into the relationship between applied loading, environmental factors, the presence of cracks and crack-like defects, and the inherent properties of the material used in components.  Many industries (eg. Aerospace, Power Generation, Automotive, Construction, etc.) rely on fracture toughness testing to aid in design of robust products that can withstand a range of service loads and environments without failure, particularly with cyclic loading conditions that are below the traditionally utilized design properties of  yield or tensile strength of the material.  This has led to improved, damage tolerant designs and safer structures. 

Fracture mechanics testing can provide quantitative results that aid in predicting crack initiation and crack growth rate.  Testing can be performed to determine linear elastic plain strain fracture toughness (K) and elastic-plastic fracture toughness (J) values that can then be used to understand how a design will respond to service conditions through application of fracture mechanics like finite element analysis (FEA).

IMR Test Labs offers accredited testing to ASTME E399 (K1c) and ASTM E1820 (J1c), among other toughness tests, utilizing state-of-the-art equipment to help with your material selection and design efforts.  Our experienced engineers can help with specimen design and test parameter selection to best assist with fracture mechanic testing needs.
