FEM modeling on interfacial debonding of single short fiber composite with elasto-plastic matrix

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

Fiber debonding in a single short fiber reinforced polymer composite is investigated by using finite element method and cohesive zone model. Fiber is modeled as isotropic and linear elastic materials and matrix is modeled as elastic material and elasto-plastic material characterized by the Ramberg-Osgood model, respectively. Fiber/matrix interface is represented by a cohesive zone model governed by the traction-separation law. The stress field of the debonded composite with elasto-plastic matrix is compared to that of the debonded composite with elastic matrix. Effect of matrix property on the debonding length is discussed.
