In this article a formulation of an anisotropic finite linear viscoelasticity model is proposed. In particular, transverse isotropy and orthotropy is considered. The aim of this work is to establish a material model, which allows the ...

Hyperelastic materials may exhibit anisotropic effects caused by fiber-reinforcement and filler-particles. In the latter case, anisotropy is induced by directional preconditioning during the production process where a microstructural ...

This paper presents several methods to examine fibre reinforced specimens at the three principle stress states and at different fibre orientations. The specimens for the different stress states were machined out of the same injection ...

The numerical simulation of the crash front in composite structures is up to now difficult. The reason is based on the complex failure phaenomena in the crushing area (fibre fracture, matrix failure, delamination, etc.). To improve ...

The increasing interest in the implementation of fiber reinforced materials for primary and secondary structures requires a closer look into the performance of these materials under a wide range of structural loads. This paper deals ...

The testing system Impetus II provides the automatic analysis of dynamic loaded parts or samples and builds for the first time a closed way of realistic material morphology and load case during test over semi analytical models or ...

Die Abschätzung der Herstellbarkeit von Tiefziehbauteilen mittels der Finiten-Elemente-Methode ist schon länger Stand der Technik. Die Genauigkeit und die Zuverlässigkeit der Simulationswerkzeuge abgebildet. Neben dieser Entwicklung ...

DYNAFORM has been known as a LS-DYNA based sheet metal forming simulation solution package. With additional development to support various manufacturing requirements, ETA has delivered a first version of DYNAFORM-DSA Module, it is ...

DYNAFORM has been evaluated through out last 12 years in 5 major overhauls. DYNAFORM 5.6 is the latest major overhault with incremental improvements and enhancements in the areas of Overall GUI reorganization, enhanced DFE features & ...

The purpose of this paper is to account for uncertainties in the manufacturing processes of metal forming in order to evaluate the random variations with the aid of FE-simulations. Various parameters of the Finite-Element model ...
