讲座摘要：
A fibre-metal laminate (FML) is a type of sandwich structure consisting of alternating layers of metal and fibre-reinforced composite. The particular interest in using these hybrid materials is linked to their attractive properties. Currently, FMLs are attracting the interest of a number of aircraft manufacturers. Here, the effort was concentrated on modelling woven glass fibre reinforced composites, as simulation of aluminium alloys is a relatively simple task. In the work presented here, a damage evolution law is incorporated into the composite constitutive behaviour to obtain the impact and blast response of FML panels. The modelling outputs for projectile impact and blast loadings are validated against the corresponding experimental results, with good correlation in terms of load displacement relationship, deformation and failure modes. The validated computer models can be used to assist design FML components suitable for different applications. Also, the current research work in Lightweight Composite Materials and Structures Group in Liverpool is briefly introduced.
