摘要：

The automotive industry requires defining restrictive criteria for prediction of technology characteristics as well as safety characteristics at car's collision with another object when auto-body components are produced from sheet metal blanks. The article presents the methodology for specification the material properties effects to overloading of human organism. Overloading depends on the geometry of the components, on the strain-hardening intensity and limit value of auto-body component's shortening that affect the component deformation path. Proposed criteria are analyzed for the following sheet metal blanks: microalloyed steel H220PD, TRIP steel RAK 40/70, duplex stainless steel, austenitic steel DIN 1.4301 and deep-drawing steel DX 54. The forming limit curves were measured by tensile test performed on the notched specimens with different notch radius. (C) 2014 The Authors. Published by Elsevier Ltd.
