FE Simulation of High Frequency Mechanical Impact (HFMI) Treatment – First Results
ABSTRACTHigh Frequency Mechanical Impact treatment is investigated numerically in the present paper. A first‐step numerical dynamic analysis is carried out using the solver LS‐Dyna. The treatment of an unnotched component of S355 is simulated. The strain rate dependent material parameter Cowper‐Symonds is calibrated for the investigated material based on data from literature. Goal of the present analysis is to act a first step for a robust engineering approach, which will calculate with sufficient preciseness the residual stresses introduced by this post‐weld treatment. The calculated residual stresses of the present investigation are compared with respective measurements found in literature. Deviation between measured and simulated residual stresses indicates the need for further improvement of the present model.
