Optical strain measurement for the mechanical characterization of polymers, and in particular of polyolefins, is becoming a common practice to determine the parameters to be used in a finite element analysis of crash problems. This ...

This talk introduces in the validation and verification process of plastics under miltiaxial loading as well as presents experimental findings of material behavior of plastics and phenomenlological modeling.

This talk gives an overiew of "Full 3D discretized", "Condensation", " Deformable Rigid Bodies" and "Coarse 3D tool meshes combined with fine active tool surface". It concludes with two examples and an outlook.

This talk's outline includes an introduction into the latest version of LS-Prepost 2.3 and several topics about metal forming application setup, user's keyword templades, drawbead modeling as well as automatic tooling positioning, the ...

The design of metal forming processes is an ambitious task in order to ensure a high quality of the subsequent products. The assessments of designs, neglecting the data uncertainty, can result in fallacious prognosis and hence lead to ...

The purpose of this study is to introduce an approach of metal cutting simulation. A Smooth Particle Hydrodynamics (SPH) based model is carried out using the LS-DYNA software. SPH is a meshless method which is very promising as a ...

The purpose of this study is to introduce the first approach of metal cutting analysis. A Lagrangian based analysis is carried out using the LS-DYNA software. Simulated cutting forces are compared with forces measured by experiments. ...

The analysis and optimization of hotforming processes necessitates the use of thermal-mechanical coupled finite element simulations. One of the key issues in process simulation is the choice of an appropriate modelling approach for ...

In contrast to the deep drawing process the Finite-Element-Method is not widely used for investigating or designing a certain bendingline. Due to the complexity of the bending process the user needs to have an understanding which ...

Superplastic Sheet Metal Forming is known since a long time, but has not established itself in Germany yet. Superplastic Sheet Metal Forming exhibits great potential regarding magnesium alloys which are marked by poor formability at ...
