Multiscale Modelling of Progressive Damage in Fiber-Reinforced Composites
A multiscale approach based upon micromechanical fiber/matrix/interface scale in fiber-reinforced composites was established to simulate the progressive damage at macroscopic scales. The composite is reinforced with Boron fibers under conditions of matrix tensile yield and interface debonding. An analytical solution using a superimposition technique within the framework of shear-lag model was employed to derive stress profiles for any configuration of breaks under applied loading. A simulation scheme coupled with Monte-Carlo method was proposed to investigate evolution of damage-plasticity of the composites.
