Improving FEM crash simulation accuracy through local thickness estimation base...
Ferreira, Vânio; Santos, Luís Paulo; Franzen, Markus; Ghouati, Omar; Simões, RicardoManuscript ; In this paper, we present a method for estimating local thickness distribution in finite element models, applied to injection molded and cast engineering parts. This method features considerable improved performance compared to two previously proposed approaches, and has been validated against thickness measured by different human operators. We also demonstrate that the use of this method for assi...
Estimating Local Part Thickness in Midplane Meshes for Finite Element Analysis
Ferreira, Vânio; Santos, Luís Paulo; Franzen, Markus; O. Ghouati, Omar; Simões, RicardoWithin the development of motor vehicles, crash safety (e.g. occupant protection, pedestrian protection, low speed damageability), is one of the most important attributes. In order to be able to fulfill the increased requirements in the framework of shorter cycle times and rising pressure to reduce costs, car manufacturers keep intensifying the use of virtual development tools such as those in the domain of Com...
Estimating local thickness for finite element analysis
Ferreira, Vânio; Santos, Luís Paulo; Simões, Ricardo; Franzen, Markus; Ghouati, OmarWithin the development of motor vehicles, crash safety is one of the most important attributes. To comply with the ever increasing requirements of shorter cycle times and costs reduction, car manufacturers keep intensifying the use of virtual development tools, such as, for crash simulations, the explicit finite element method (FEM). The accuracy of the simulation process is highly dependent on the accuracy of ...
