报告摘要：
Composite materials are finding increasing utilisation in a number of transportation industries concerned with making structures lighter to reduce environmental impact and improve efficiency. A homogenised mesoscale approach for intralaminar (ply-level) damage based on continuum damage and fracture mechanics has been developed. The intralaminar damage model accounts for tensile and compressive failure mechanisms, of the fibres and matrix, associated with a full three-dimensional stress state. Cohesive zone model is employed to model the interlaminar failure between plies with a bi-linear traction-separation law for damage onset and subsequent damage evolution. The virtual tests set up in ABAQUS/Explicit were executed to predict low-velocity impact damage and compression after impact CAI strength of composite laminates (Fig.1), as well as the behaviour of composite laminates under crush loading (Fig.2). Numerical predictions are shown to agree fairly well with experimental results, thus demonstrating a reliable tool for virtual testing of composite structures.
