ALE Incompressible Fluid in LS-DYNA
The computation of fluid forces acting on a rigid or deformable structure constitutes a major problem in fluid-structure interaction. However, the majority of numerical tests consists in using two different codes to separately solve ...

User-Defined Nonlocal Models in LS-DYNA
In this paper, we present an implementation technique that aims to easily incor- porate the benefits of a nonlocal formulation to existing local constitutive models. In order to avoid pathological mesh dependency, an approximation of ...

About Isogeometric Analysis and the new NURBS-based Finite Elements in LS-DYNA
In the context of isogeometric analysis many research activities have focused on the use of Non-Uniform Rational B-Splines (NURBS). These NURBS-based finite elements have been studied in depth and it has been shown, that they are ...

Hypervelocity impact of aluminium sphere against aluminium plate: experiment and LS-DYNA correlation
High velocity impact of 3 mm diameter aluminium sphere against thin aluminium target plate has been performed at impact velocity of about 4000 m/s with the two stage light gas gun HERMES at Thiot Ingenierie laboratory. Impacts at ...

Simulation of charge and structure behaviour in a tumbling mill
For a long time discrete element methods (DEM) has been used as simulation tools to gain insight into particulate flow processes. Such a process may be grinding in tumbling mills, where the mechanical behaviour is complex. To include ...
