Fracture Mechanics and Toughness   Testing Services


Fracture mechanics testing can provide quantitative analytical results that aid in predicting crack initiation and crack growth rate.

Fracture toughness testing provides great insight into the relationship between applied loading, environmental factors, the presence of cracks and crack-like defects, and the physical properties of the material used in components.

IMR Test Labs offers accredited testing to ASTME E399 (K1c) and ASTM E1820 (J1c), among other toughness tests.  Our experienced engineers can help with specimen design and test parameter selection to best assist with fracture mechanic testing needs.
