Abstract Manufacturing problems resulting from lubricant supplier changes are relatively common in automotive press shops. Simulations using computer-aided design (process and tool) detect a significant proportion of manufacturing before tools physically produced. In modern forming codes, an enhanced Coulomb model is used to numerically the friction phenomena associated with lubrication. labora...

Abstract Today, the hardening Yoshida-Uemori model is implemented in most used FEA stamping codes (Autoform®, Pamstamp®, LS-Dyna®…) with occasionally some variations. This forming material card requested regularly by car manufacturers. The a combined coupled elastic evolution modulus which depends on equivalent plastic strain. According to experimental tests conducted and their identification p...

Abstract The increasing demands on part complexity and tailored properties in form of local strength ductility cannot be achieved with conventionally manufactured hot stamped body components. To meet the requirements safety-relevant parts, partial stamping is increasingly used automotive industry. One approach to achieve parts based controlled cooling blank prior forming quenching. related furn...
