This crashworthiness optimization study compares the use of three metamodeling techniques while using a sequential random search method as a control procedure. The three methods applied are (i) the original Successive Linear Response ...

Smart materials and smart structural concepts in flow control have the potential for significant impact on the design and performance of modern turbocompressors. While the benefits of an airfoil whose geometry is variable were ...

Numerical problems due to element distortions limit the applicability of a Lagrangian description of motion when modeling large deformation processes. An alternative technique is the multi-material Eulerian formulation. It is a method ...

In this this paper, we describe main results obtained within the scope of joint project activities concerning the numerical simulation of reacting flows in complex geometries. The aim is the refinement of numerical methods for applied ...

The physiology and anatomy of the human body is so complicated that viable simu- lations of even only parts of it require severe simplification. Accordingly, for our work on the mechanics of natural and replacement aortic heart ...

In the rare event of a fan blade separation, the fan blade must not penetrate the case of a commercial jet engine. Due to this requirement the fan case is the heaviest single component of a jet engine. With a goal of reducing that ...

The Discrete Shear Gap Method, initially proposed for the elimination of transverse shear locking in plate and shell finite elements is extended to a more general concept, applicable to other locking problems, typically causing severe ...

LS-DYNA provides several beam element formulations, see the keyword description for *Section_Beam in the User’s Manual. Several of these beam element formulations support user supplied integration of the cross section, via the ...

This paper focuses on the finite element simulation of two full-scale tests of high performance, seismic-resistant structural frames using the LS-DYNA 960 implicit solver. The frame was physically tested as part of the design ...

This presentation gives you an overview of how all these impicit features were implemented, an overview of onging development of an MPP implicit capability and integrated implicit with explicit code.
