Study on the forming fracture of the crash box with extruded Al6060-T6 profile

This study was performed to analyze the forming fracture of crash box with extruded Al6060-T6 profile. Deep drawing test evaluate formability For various specimens, deep tests were repeated measure maximum stroke at which did not occur. The finite element analysis for calculate principal strain through obtained stroke. limit diagram design concave shape calculated strains FEA. optimized by using variables and FLD are central curvature, lateral depth. tools made optimizing model has been formed without fracture.
