The fatigue FEM analysis normally cannot inherit the stamping effects due to heterogeneous codes used. This paper proposes a database modification approach to integrate the stamping effects into the fatigue FEM prediction for an engine bracket in an accelerated rig test. Equal thickness shell, unequal thickness shell (including the stamping effects) and solid element are used to simulate the tubular...
Tube hydroforming has recently drawn the attention of the automotive industries due to its several advantages over conventional forming methods. For a given blank tube and part design, the success of tube hydroforming process is highly dependent on the loading paths (axial feeding versus internal pressure). To obtain a part with the required shape and minimize the tube wall thickness variation during...
