Modelling and predicting spotweld failures in automotive crash structures

Wood, Paul and Schley, C.A. and Beaumont, R. and Walker, B. and Dutton, T. and Buckley, M.A. (2009) Modelling and predicting spotweld failures in automotive crash structures. In: 7th European LS-DYNA Conference, 2009-05-14 - 2009-05-15.

Abstract

The project has developed spotweld failure models capable of industry application for a range of steel grades to support development of automotive products, and their compliance to interntional crash safety requirements. An important consideration in this project is a requirement to balance the cost to develop the data input to models and their application capability in CAE based crash simulation tools to predict spotweld failures.
