Abstract

The Riera approach is the most commonly used method for modelling the global effects of a deformable missile on a rigid engineering structure. The Riera approach assumes the normal impact of a rigid perfectly plastic missile that only crushes at the cross-section adjacent to the target. It also neglects the effects of target deformation. Our research focuses on analysing the limits of the applicability of the Riera model by comparing its results to that of a finite element (FE) model. Different initial parameters of impact, missile and target are considered over a wide range of values. Keywords: aircraft impact, global effect, Riera-approach.

Keywords
