? Formed parts undergo thinning and plastic Deformation
? The method of taking this into account in crash models is well established
? Conduct test to deform the part at damage location induced during forming.
? Perform forming and crash simulation to duplicate test and demonstrate effect of damage by comparing failure with and without damage .
