An Investigation of Interfacial Fracture Using Experiments, Modeling, and Simulation

Abstract

The behavior of a bimaterial specimen consisting of a rubbery particulate composite with a thin rubber layer is studied experimentally and computationally. The purpose of the investigation is to study the behavior so fracture in the rubber material can be understood better. The paper uses computer-aided speckle interferometry to interrogate specimens deformed using tensile testing. Computational modeling of the specimens is also addressed. Key findings are different behavior for the two materials, the presence of an intermediate region, and delamination sites that are dependent on specimen geometry.
