Modelling and analysis of simulated lightning strike tests: A review

Aircraft are increasingly being made of electrically resistive composites, rather than conductive metals. Therefore, it is important to analyse the damage caused by a lightning strike. Given the benefits of simulations over experimental analysis in terms of cost and specialist test infrastructure required, simulations have become increasingly important in the analysis of lightning strike damage. Preceding review articles have focused on lightning strike protection of composites and an initial review of the physics, problem formulations, and numerical approaches for multiphysics analyses for simulating lightning strikes. However, none have systematically critiqued and contrasted the lightning strike simulations used in literature to date. Therefore, this review paper focusses on the modelling and simulation approaches within literature, paying particular attention to their material properties, construction, loading strategies, meshing approaches, solutions and results. The current and proposed lightning strike modelling approaches are discussed along with their current limitations and future challenges.

Automated summary

This article focuses on the increasing use of electrically resistive composites in aircrafts, the importance of analysing lightning strike damage, and the role of simulations in this analysis. It reviews the modeling and simulation approaches in literature, particularly focusing on material properties, construction, loading strategies, meshing methods, and results. Discussions on current and proposed lightning strike modeling approaches, along with their limitations and future challenges, are also presented.
