Abstract

A finite element approach to analyzing a deep piercing process is presented. In the approach, the element deletion scheme after the element degradation scheme is employed to predict the piercing phenomenon because the time interval between piercing initiation time and final stroke is quite large. The normalized Cockcroft-Latham damage model is used and an assumed flow stress smoothing function is used to reflect the effect of cumulative damage on the flow stress, i.e., to designate the degree of element degradation due to damage. The approach is applied to a deep piercing process of which aspect ratio of plate thickness to hole diameter is 5.0. The comparison between simulation and experiment shows a good qualitative agreement with each other.
