Elastoviscoplasticity with aging in aluminium alloys

Abstract : After two decades of intense activity on constitutive equations and integration algorithms in the research laboratories, news methods are now available for engineers who need numerical tools for the design of critical components working at high temperature. Due to the increase of computer power, this approach (computation of the actual stress-strain state, then creep-fatigue damage modeling) should progressively replace the classical design method, based on elastic computations followed by plastic corrections, and reduce the number of prototypes, thus the duration of the development. The present paper shows an application of the method to the cylinder head of car engines.
