Continuum damage mechanics is used to model crack initiation as well as crack propagation in metal forming simulations. For this purpose, a gradient damage formulation is coupled to an existing largestrain elastoplasticity framework. The resulting equations are solved by the finite element method. Crack initiation and crack growth are traced using remeshing. The numerical framework has been successfully used to model metal forming operations in two dimensions. Aspects of the -far from trivial -extension to three dimensions are discussed.
