A pragmatic orthotropic elasticity-based damage model with spatially distributed properties applied to short glass-fibre reinforced polymers

This article presents a simple progressive damage model for quasi-brittle materials, combining orthotropic elasticity with scalar including spatial variation of the initiation strain and crack band method softening regularization. The model’s performance is first analyzed from numerical point view then demonstrated tensile tests ( 0 ° , 45 90 ), open-hole ) three-point bending short fibre-reinforced polypropylene 15 wt.% 30 glass fibres. Despite its simplicity, captures anisotropic elastic inelastic behaviour observed in experiments. applicable brittle or where variability properties negligible orientation dependency fracture small not relevant application.
