The detonation of an explosive charge has two major effects, blast wave generation and fragmentation. New technologies of energy dissipation, based on granular materials, seem to have good shock attenuation capabilities. Plastic ...

The behaviour of aluminium foam under impact loading conditions and especially the shock wave propagation are still not well understood. The shock wave propagation through the cellular material structure under impact loading ...

A solution had to be found in order to protect buildings neighboring an industrial site from the blast effects of possible accidental explosions on the site. One of the main issues was that the point of detonation would occur ...

This paper is concerned by the effect of HE geometry on the shape of the blast wave. The aim of this work is to increase the knowledge on pressure profile generated by blast wave so as to optimize the design of explosion chambers. ...

This talk introduces into the statement of the issue as well as the technical solution. It presents an example and concludes with a summary.

The robustness of production processes and the quality of resulting products suffer from variations in important material and process parameters, geometry and external influences, which can have substantial and critical influences. ...

Titanium alloys have excellent properties for their target applications; however their use is still limited by high price and formability issues. To avoid extensive on-site trials and to cut development costs, a numerical simulation ...

Despite their wide application in sheet metal forming analysis, Forming Limit Diagrams cannot supply reliable results for the cases involving non-proportional strain paths or material classes with reduced ductility such as advanced ...

The “direct” heat transfer problem is one in which material properties and boundary conditions are specified, and LS-DYNA [1] is used to calculate the temperature response of the nodes in the mesh. The “inverse” heat transfer problem ...

This talk gives an insight into preparation of test specimens, measuring equipment and test results as well as material and FE models and parameter identification. It concludes with a discussion about the simulation results.
