Cell models with either single fibre or multiple fibres were modelled by extended finite element method (XFEM). The damage progress in the cells was investigated and then the nominal stress-strain curves as well as stress distributions in the fibre and matrix were obtained. Results presented here indicate that the extended finite element method is an effective modelling technique to study the initiation and propagation of a crack along an arbitrary, mesh-independent, solution-dependent path.Keywords: Damage evolution; Damage propagation; Extended finite element method; Fibre reinforced composites; Micro-mechanical modelling; Composite micromechanics; Crack propagation; Fiber reinforced plastics; Fibers; Glass fibers; Stress concentration; Stress-strai Damage evolution; Damage propagation; Extended finite element method; Fibre reinforced composites; Micromechanical modelling201110.4028/www.scientific.net/AMR.152-153.732016-02-24
