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 ...

The aim of the cross-roll straightening process is to straighten bars having a circular section. To the knowledge of the authors, most of the work published about this process is based on analytical considerations. In the present ...

Incremental CNC sheet forming (ISF) and incremental sheet forming with incremental die (ISFID) are relatively new sheet form process for small batch production and prototyping. In these processes, a blank is shaped by the CNC ...

There is an increasing demand for car body parts made of high strength steels nowadays. The prediction of forces needed for stamping these parts is very difficult due to elastic deformations of the tools and presses. These ...

The rise in the light weight automotive design necessitates the usage of the high strength steels, which increase the springback tendency in the sheet metal forming. Contrary to the conventional steels, the high strength steels ...
