Abstract

We assess the use of the Pam--Crash bi-phase failure model for the explicit finite element impact analysis of preloaded composite plates. The results obtained were compared with experimental work to corroborate the accuracy of the model. Overall, the trends displayed in the finite element simulations were consistent with experimental data, although quantitatively finite element results were conservative. The development of the model raised a number of issues concerning the accuracy and limitations of modelling techniques available.
