“…The idea was to produce forming results of reasonable accuracy with little effort. It has been reported that one-step solvers are useful in an early stage of product design before tooling information is available [4,5]. The tool modelling can be skipped with a one-step solver, since the deformation is calculated backwards from the final shape of a part.…”

“…We wanted to select a formulation that can give reasonably detailed estimates for the overall conditions in the formed part while not requiring large effort for modeling all the details of the forming process. The One-Step Forming Method [39,40] fits this overall objective while providing reasonable accuracy [41]. One-Step Method is commonly used in steel industry at the product design stage for quick evaluation of manufacturing feasibility without considerable investing into die design.…”

The objective of the research was to perform a comprehensive computational analysis of the effects of material and process modeling approaches on performance of Ultra Light Steel Auto Body (ULSAB) vehicle models. The research addressed numerous material related effects, impact conditions as well as analyzed the performance of the ULSAB vehicles in crashes against designs representing the current US vehicle fleet. Crash modeling simulations show a clear effect of strain-rate sensitivity on high strength steel (HSS) intensive vehicle. The influence of a strain-rate model can be an incremental sensitivity due to the increased flow stress when similar structure collapse modes are predicted. However, significant differences in crash energy management capacity can be predicted if the change in loading on members alters the predicted collapse mode of the structure. From the material substitution study it can be concluded that HSS material substitution cannot be performed on the basis of the material yield point only and that, especially for advanced HSS vehicle designs, the entire region of material plastic response has to be considered. However, the problem of modeling of the overall dynamic crush process still remains open and requires further experimental and theoretical investigation. Crash modeling simulations show a moderate effect of forming on overall crash performance. The design is the determining factor on the vehicle performance and, therefore, the results of this research cannot provide measures that can be used in a general case. However, it has been shown that for materials that have modest strain hardening, the forming effect is observable and that when more complex forming Page 1 of 2 operations are used, especially in combination with rapid strain hardening materials, forming effects should be taken in the consideration in the computational crash models. Crash compatibility study between ULSAB and cars of similar geometric characteristics have shown that the ULSAB design is compatible with the conventional designs of existing cars with similar inertia and geometric characteristics. The structuralperformance characteristics of the vehicles involved in a car-to-car collision when one of the cars is the ULSAB are governed by the stiffness and geometry of the crush zone in the vehicles. The effects of mass could not be evaluated because of the similar mass of the vehicle models used in the analysis. Within the constraints of the current analysis it appears that, for the ULSAB, the effects of stiffness dominate the compatibility aspects for collisions with similar vehicles.
