Material Failure

This two-day seminar will discuss issues related to the adjustment of material models considering the failure, which can sometimes be relatively complex. The seminar intends to look at the complete picture, reaching from the approach to test design to the actual creation of a material card using LS-DYNA, thus reflecting the entire verification and validation process.

In more detail, the conversion of test data to real stress and expansion values will be explained, as well as the dependencies of deformation patterns on anisotropy and tri-axial condition, including complex descriptions of failure. In addition, the seminar intends to explain, in particular, the influence of model reduction in shell elements, using descriptions of failure. e.g. according to Wierzbicki, on the basis of Gurson, Johnson-Cook and extended Barlat models. The influence of the dependency on element size will be discussed in the context of expansion and energy equivalence. The issues of material stability and strength loss will be discussed in detail using the Gurson material model. Exercise examples illustrate the theoretical findings.
