Finite element simulation of crack growth in blanking process using floating collapsed elements

Numerical simulations of fine blanking process using various finite element methods are presented in this work. In this paper the crack propagation process is simulated using a combined collapsed mesh generation system. A block of collapsed elements is used around the crack tip to increase the density of elements and accuracy of calculation. Remeshing is executed during the analysis. The collapsed block is moved in each mesh generation step so that its location is always around the crack tip. The results of this method are compared with the results of other F.E. simulations which have already been published. The results of simulations are presented for both fine and conventional blanking processes. (authors)
