Abstract:Damage and fracture are important criteria in the design of products and processes. Damage models can be used to predict ductile failure in metal forming processes. Nonlocal models avoid the mesh dependency problems of local damage models. A nonlocal damage model has been implemented in LSDYNA using the user-subroutines UMAT and UCTRL1. The implemented model will be compared with
results obtained with the available option in LS-DYNA to combine *MAT PLASTICITY WITH DAMAGE with *MAT NONLOCAL. Advantages and disadvantages of the different implementations will be discussed. The user nonlocal damage model has been applied to a bending and a blanking process. Results of these simulations will be shown.
