Abstract

In the Automotive industry there is a need for weight reduction in order to reduce the Energy consumption, ????????2 emissions and also the need for high safety, which has led to the use of high strength steels because of their light weight and high strength properties. The increasing demand of high strength steels and short development time has led to the requirement of improved predictions of the actual crash behavior in the automotive industry because a full-scale crash test is both expensive and time consuming. The models used for crash simulations are usually isotropic and is based on the Gurson, Tvergaard & Needleman or the von Mises flow rule. GISSMO is the damage model has been developed at Daimler and DYNAmore used in such crashworthiness simulations. This paper is mostly based on the reference of various LS-DYNA User conferences. GISSMO damage model has a number of parameters and curves that defines when necking and failure occurs. GISSMO is a phenomenological damage mechanics model which is based on experimental results and does not consider voids and cracks
