Abstract

This paper is focused on detailed simulations of glass fibre laminates under static loading using Abaqus/Standard and Abaqus/Explicit (quasi-static). Failure criteria in quasi-static analysis for beams cover both shear failure and tensile failure, which are capable of modelling brittle fibre failure and the post-failure of the beam. For glass fibre laminated panels subjected to static perforation load, the Hill Potential criterion was used to simulate the panel up to the peak load. Material properties obtained from uniaxial tension and bending tests were implemented to the numerical modelling. In order to validate the model, panels made with 4-ply, 8-ply and 16-ply glass fibre laminates were subjected to static projectile loading, beams made with 16-ply glass fibre laminates were subjected to three-point bending, respectively. Reasonably good correlation was obtained between the simulated and experimental load-deflection relationships and failure modes. The model developed is suitable for simulating fibre composites under static loading.
