Abstract

Copper based Shape Memory Alloys (SMAs) possess good Shape Memory Effect (SME) and Superelasticity and the alloys are prone to corrosion due to atmospheric conditions. The SMAs absorb hydrogen which results in hydrogen embrittlement which affects the SMAs characteristics. The fracture toughness of the hydrogen embrittled alloys were estimated for compositions of ternary Alloy-Beryllium (0.47 by weight %) under uniaxial tensile testing (Mode –I type). Strain energy release rate and Stress Intensity factors were determined. 0.47 wt. % of Be in the SMA has the higher fracture toughness and the stress Intensity factor is directly proportional and strain energy release rate is inversely proportional with the increase in Crack length.
