Volvo Adopting Safer Advanced Material: Metal Stamping, Cast Parts Predictability
To create a numerical simulation model, that covers all the complex conditions involved in crash situation, Volvo 3P uses the Altair software RADIOSS. In the need to study several aspects such as elasto-plastic behavior, hardening, strain rate dependency, triaxial behavior and failure, Volvo 3P relies on the modeling capabilities of RADIOSS. Several tests for material property identification were accomplished to obtain data about the material's behavior up to the rupture in case of torsion, tension and compression (hardening, strain rate effect, stress state influence). The achieved data were used to validate the numeric model in RADIOSS and enabled the Volvo 3P engineers to set up the right material laws for simulation.
"We are pleased to see Volvo 3P Cab Engineering engineers expanding the usability of RADIOSS in their development tasks," said Mauro Guglielminotti, managing director, Altair, France. "Having the ability to better predict crash results is a highly competitive advantage and will lead to better and safer products, a reduced number of prototypes and savings of time and money. Including special validated material laws is the right answer to the calculation needs at Volvo 3P Cab Engineering."
About RADIOSS
RADIOSS is a next-generation finite element solver for linear and non-linear simulations. It can be used to simulate structures, fluids, fluid-structure interaction, sheet metal stamping, and mechanical systems. This robust, multidisciplinary solution allows manufacturers to maximize durability, noise and vibration performance, crashworthiness, safety, and manufacturability of designs to bring innovative products to market faster.

"The prediction of the behavior of single components can be very complex, as recently shown by the prediction of crash behavior for ductile cast-iron brackets," said Jerome Lagrut, senior analyst, Volvo 3P Cab Engineering. "Since the brackets are the critical link between chassis and the driver's cab, they are key components for the crash behavior and the occupant safety. Certain crashworthiness requirements, such as regulations and severe internal requirements must be covered. After the identification of the material behavior via tests, we have been able to implement these laws in a simulation model for further investigations. The crash simulations on complete vehicles in RADIOSS showed very good correlations with physical tests and we are very pleased with the outcome of our development efforts," he continued.
