AB - In order to establish the survivability of a composite panel in an impact scenario it is important to be able to predict the damage incurred and the effect of the contact force. The damage caused by low velocity impact is barely visible and a hidden menace and for thick plates transverse stresses are significant in promoting delamination. In the present work woven vinyl-ester composite plates up to 1.37m long are numerically modelled with a simple, gradually damaging three dimensional material model and the results are compared with full-scale tests. The model is based on damage mechanics principles using cyclic test data to obtain modulus reduction with damage. Delamination is modeled with a mixed-mode traction-separation law using cohesive elements. The non-linear elastic orthotropic material model for the woven plies is written in a VUMAT subroutine in Abaqus/Explicit and the effects of varying some of the modelling parameters are briefly discussed through the examination of the contact force.
