Abstract

This paper presents a finite element formulation of elasticity to model elastic fracture in composites with long aligned fibers. We have employed a B-bar type approach which is applicable to compressible as well as nearly incompressible material systems. An energy approach is undertaken to evaluate the stress intensity factor at the crack tip. The effects of strong intact bridging fibers, fibers ahead of the crack tip, and that of temperature variation on the reduction in stress intensity factor at the crack tip have been investigated. Various numerical results are presented to show fiber-fiber and fiber-crack interaction.
