Abstract

Modern approaches to exploring the impact behaviour of composite components involve computer models such that the components are virtually tested. However, for these virtual tests to be trusted they require careful validation using experimental data. This study demonstrates a quantitative validation approach for confirming the effectiveness of a simplified impact model. A set of six asymmetric laminates was impacted at 30 J whilst their bottom surface was monitored using high-speed cameras. The camera images were processed to obtain full-field strain which was then used to validate the model by the orthogonal decomposition technique. The validation procedure has confirmed that the model provides reasonable predictions of impact behaviour and gives insights into how it could be improved. The overall approach demonstrates how virtual testing of composite components can be vigorously validated. Validated virtual testing can then provide a low-cost and rapid route to the certification of lightweight composite structures.
