this work is an attempt towards employing ductile damage criterion and finite elementsimulations for prediction of fracture initiation and evolution in deep drawing of copper/stainlesssteel clad sheets. the material mechanical properties and ductile damage parameters weredetermined through standard and notched tensile tests. the effect of some important processparameters on damage evolution wer...

In this paper, the energy absorption features of tri-layer explosive-welded deep-drawn cups subjected to quasi-static axial compressive loading are investigated numerically and experimentally. To produce the cups, tri-layer blanks composed of aluminum and stainless steel alloys were fabricated by an explosive-welding process and formed by a deep drawing setup. The quasi-static tests were carrie...

The competition among sheet-metal-forming manufacturers in recent years has become more severe. Many have survived by cutting their production costs. Increasing the formability, which could reduce costs, is focus of many and engineers. In present research, to increase formability over limiting drawing ratio (LDR) cylindrical deep-drawing process, application oleophobic coating proposed. An SUS3...
