A new multiscale modeling approach, involving the use of combined precipitation, yield strength, work-hardening, and mechanical models, has been devised that proved useful to optimize the load-bearing capacity of welded crash components made of age-hardening Al-Mg-Si alloys. The main parameters that influence the structural performance are, in addition to geometry and boundary conditions, the following: 1) alloy composition; 2) initial base plate temper condition; 3) applied heat input during welding; and 4) subsequent postweld heat-treatment schedule all being fully accounted for in the numerical simulations.
