This paper focuses on modelling the deflection of Carbon Fibre Reinforced Polymer (CFRP) and aluminium panels when subjected to forces generated by a lightning current flowing through them. Accurate quantification of the deflection of a CFRP plate under a lightning strike is important as this may exacerbate deterioration of the CFRP material and compromise its mechanical and electrical properties. In order to predict plate deflection accurately, there are several parameters that need to be taken into account within an electromechanical model, and these include; current amplitude and injection point, CFRP sample geometry and layup, electrical conductivity, and mechanical properties (Young's modulus and Poisson's ratio). In this paper, models of a set of quasi-isotropic layers in a multi-layup CFRP plate and an aluminium plate were constructed. The simulation results of the modelled plates show that deflection increases with current amplitude as higher stresses are generated. However, the deflection decreases as the number of plies and material stiffness increase. Over the parameter range that was considered in this study, no significant change in sample deflection was seen with electrical conductivity. The results also confirmed that deflection is largest at the current injection point and that the greatest deflection occurs when the injection point is at the centre point of the sample.
