Fracture Mechanics Approach to Adhesive Joints,

Abstract

The problem of applying fracture mechanics to the opening mode fracture of a two- material, aluminum-epoxy-aluminum, system was investigated. A finite element analysis is used to determine the strain energy rates and stress intensity factors for the two- material, single-edge-notch (SEN) system with adhesive layers of various thicknesses. Approximate relationships between the homogenous system and the adhesive system for both the strain energy rates and stress intensity factor are determined. Good reproducibility of the fracture toughness values obtained for the two-material system with SEN and tapered double cantilever beam specimens indicates the geometry independence of the fracture toughness.
