A photoelastic and FEM analysis of interfacial crack propagation
Department of Mechanical Engineering-Engineering Mechanics
The linear elastic solution for the bimaterial interface crack is applied to determine the direction of crack propagation during surface-layer removal by scraping. The direction of the load which must be applied to the free end of the surface layer for continued interfacial crack propagation is determined using photoelasticity and finite elements, and results are found to be in good agreement.
