User Defined Materials in LS-DYNA

The user defined material model interface allows a possibility for the user to implement own material models and link it to a version of LS-DYNA. This requires some knowledge of Fortran 77 as well as numerical schemes for updating e.g. stresses and material histories. The course addresses the industry as well as academics and serves as a basis for users that want to get started in user defined material modelling in LS-DYNA.
