The numerical simulation of structural parts made from polymers is becoming increasingly important. Although highly sophisticated material laws are available in commercial finite element programs, there are still open questions, especially for crashworthiness analysis. In this paper, we restrict our attention to the explicit solver of LS-DYNA, see [1] and [2]. However, the results are transfera...

A description of lifetime shock tests on tantalum and tungsten is given and of modelling studies as part of the research into solid targets for a Neutrino Factory. A fast high current pulse is applied to a thin wire of the sample material and the number of pulses measured before the wire visibly deteriorates. These measurements are made at temperatures up to 2000 K. The stress on the wire is ca...

The circular saw blade is widely applied in rock processing; its cutting performance significantly impacts processing. Therefore, the numerical simulation model of with flexible has been established to investigate effects parameters on stress and force blade, damage into vertically at constant feed speed rotation speed. research results indicate that rises increase blade. Furthermore, increasin...

The bow flare slamming load was studied by using the software Ls-dyna. A coupling finite element model including air, water and 3d established. Flare pressure picked up from in order to discuss relation between velocity as well distribution rule of different entry angle along length height ship.

This paper is concerned with closing a gap in the process chain of metal forming. Tools for simulating the metal forming process like LS-DYNA® produce output geometries and stress information which cannot be easily re-imported in CADSystems or structure analysis programs for further processing. A concept has been developed and implemented with a corresponding program which allows the re-importa...

In order to identify the engine inlet oil film parameters more accurately, the oil film identification equation based on oil film model is built under the consideration of random error which is consisted by model error and measurement error. For the purpose of eliminating the influence of random error to the identification results, Recursive Auxiliary Variable (RAV) is put forward. At the same ...
