Effects of Damage on Interfacial Crack Tip Fields

Abstract

Critical cracks can form along or near the interface between two rubbery particulate composite materials. Damage near these cracks can affect the shape and size of the crack tip fields in the two materials. In this study, finite elements are used to simulate damage near an interfacial crack tip to discover how this damage affects the crack tip fields. The effects of damage zones of different sizes on the magnitude and phase angle of the complex stress intensity factor are studied.
