Abstract

The purpose of this paper is to present a proposal for the design of steel structures sensitive to buckling to fill the gaps in the current Standard EN 1993-1-1, providing guidelines to obtain the magnitude of the imperfection generalizing the procedure given in clause 5.3.2(11) [...]

Abstract

The tool setting process of a rotary draw-bending process is very complex. Only experienced machine operators know which settings lead to a good result in relation to the bending task. Up to seven individual tools can be installed, positioned and set in the process independently. [...]

Abstract

In this paper, we firstly introduce a nodal-integration-based finite element method. The method allows the use of first-order tetrahedral elements without suffering from the volumetric locking problem. The most important advantage of tetrahedral meshes is that they can be automatically [...]

Abstract

In the development and manufacturing process of modern cars, cables and hoses are important system components. In automotive industry, virtual assembly planning and digital validation of system layouts require a fast and physically correct simulation of the mechanical behavior [...]

Abstract

Nowadays, industrial processes like sheet metal bending or punching are performed with high precision. Further optimizations are only possible by simulation and appropriate material models and parameters. Goal of this work is to find a material model suitable for both, bending and [...]

Abstract

Additive manufacturing with FFF (Fused Filament Fabrication) technology using continuous fibre, allows more complex structure designs with more technical materials than conventional manufacturing processes. The present paper is focused on analysing the bending behaviour of sandwich [...]
