Predicting the crack initiation fracture toughness for a crack along the bimaterial interface

Three Point Bend (3PB) bimaterial specimens of PMMA/PC were made by joining the two materials using friction welding. The specimens were tested and the crack initiation loads were recorded to evaluate the K using ASTM standard E 1820-01. Stress field in the crack tip vicinity was studied using finit...
