Abstract

This chapter proposes a systematic simulation strategy to determine the mechanical behaviour of composite laminates under impact loading using a computational mesomechanics approach. The methodology includes modelization of the physical mechanisms of damage observed in laminates: intralaminar (ply failure) and interlaminar (delamination failure). The methodology was applied to analyse the impact behaviour of carbon–epoxy laminates subjected to low- and high-velocity impacts, and the results were ...
