Abstract

In this work, a computational method dedicates to realize the residual stress calculation for multi depths with incremental hole-drilling method. An optimized finite element model is determined with proper size compared to the experiment. By invaliding the mechanical properties of the drilled section in the model, the step-by-step drilling procedure is simulated for incremental hole-drilling method. As the practical application of such computational method, a bulk metallic glass (BMG) sample being mechanically treated by severe plastic process is used to demonstrate the distribution of residual stresses along thickness direction.
