Stamping processes induce plastic strain and changes in the thickness, shape and
mechanical behaviour of sheet metal parts. Simulated crash tests on vehicles should …

The objective of this thesis work has been to transfer metal forming simulation parameters
(effective plastic strain distribution, thickness and residual stresses) into the crash simulation …

To improve the accuracy of crashworthiness simulation, it is preferable to consider the
effects of metal forming. However, this approach was difficult in practice since analyzing the …

The thickness changes and work hardening arising during the forming process are generally
ignored in crash analysis. However, LS-DYNA offers a number of options for quantifying …

The influence of back stresses during forming processes of sheet parts on subsequent
crashworthiness is investigated in this article. To this aim, the simulation results of crash …

Forming and strain rate effects on crashworthiness of automotive body components were
investigated in this study. Dynamic tensile tests were carried out to establish the stress-strain …

The objective of the research was to perform a comprehensive computational analysis of the
effects of material and process modeling approaches on performance of UltraLight Steel …

The development of numerical models for the simulation of the mechanical behavior of
structures in various possible accident scenarios of is therefore a major objective of present …

The ballistic resistance of 2024-T3 and 2024-T351 alloy aluminum flat plates to aircraft
engine fragments is evaluated experimentally. Gas and powder gun tests are performed to …

Manufacturing of a bumper system from aluminium extrusions often involves series of
forming operations performed in the soft W-temper condition, and then artificially age …
