...-phase (CP), TWIP, and austenitic stainless steel (AUST SS) grades due to their high toughness. Crashworthiness is characterized by the total energy that a structure can absorb. One way to assess crashworthiness is to monitor the folding pattern of a thin-walled structure subjected to a crushing...
