The *INTERFACE_SPRINGBACK card allows LS-DYNA to conveniently export deformed geometry, member stresses and effective plastic strains from one analysis run to another. This facilitates the use of inexpensive implicit analyses to ...

In this contribution, new anisotropic elastic-viscoplastic constitutive models for simulating unidirectional reinforced fiber matrix composites and textile fabrics are presented. These are in particular a transversely-isotropic ...

Structural mechanic properties of fiber reinforced plastics depend on the single components’ properties, namely matrix and fiber. Simple Micromechanical homogenization theories reach a limit when a laminate consists of fabric ...

Since the mid nineties sheet metal forming simulation has been widely used to take the uncertainty out of the die design process. When forming simulation was first introduced into the work of die designers the main focus was on the ...

Since March 2011, a newly released Federal Motor Vehicle Safety Standard 226 Ejection Mitigation (FMVSS 226) shall help to reduce the complete or partial ejection of vehicle occupants through side windows during rollover or side ...

*MAT_251 (*MAT_TAILORED_PROPERTIES) ist ein Material-Modell, das über einen Table 3D lokal unterschiedliche Spannungs-Dehnungs-Verläufe in Abhängigkeit von einer History-Variablen berücksichtigen kann. Diese History-Variable wird ...

The initialisation of stresses due to gravity or manufacture can often be ignored when the item concerned is subjected to an impact such that the stresses induced by the impact are significantly higher than those from any pre-stress. ...

Die virtuelle Produktentwicklung hat sich in den vergangenen ein bis zwei Jahrzehnten fest etabliert. CA-Tools sind aus der Welt der Entwickler, Berechner, Planer und aller weiterer am PLM-Prozess beteiligten Bereiche nicht mehr ...

Der Einsatz von Computertomographie und 3D-Laserscan eröffnen neue Möglichkeiten bei der Dummymodellierung. Damit sind detaillierte Aussagen über Geometrie, Materialübergänge und produktionsbedingte Unterschiede möglich. Der ...

The design process in engineering takes place for a high-dimensional input space with few result parameters. The calculation of these result parameters is due to the corresponding nonlinear deterministic simulation time-consuming. ...
