Purpose: The purpose of this paper is to examine quadratic convergence of finite element analysis for hyperelastic material at finite strains via Abaqus-UMAT as well as classification of the rates of convergence for iterative ...

Several methods for the determination of integral damage in sheet metal are reviewed and investigated at the example of the ferritic steel DC04. A novel method to determine damage in cylindrical rings is proposed. Such a ...

In order to improve the cutting performance of PcBN tools, the cutting edge is prepared e.g. by grinding or brushing. Since PcBN is the second hardest material besides diamond, mechanical preparation of PcBN tools is ...

One possibility to adjust tailored properties in hot stamping is the application of a masking concept to prevent a complete austenitization. In this study different concepts were investigated in order to use them as a ...

In combustion engines a large percentage of mechanical losses result from friction, for example within the cylinder liner. In order to reduce the friction between cylinder liner and piston, micro dimples in the surface ...

Lithium ion batteries (LIBs) are at present widely used as energy storage and conversion device in our daily life. However, due to the limited power density, the application of LIBs is still restricted in some areas such ...

This paper aims to model the progressive damage of multi-bolted joints connecting structural elements made up of FRP (fiber- reinforced polymers) composite laminates and comprising different fiber materials (namely, based ...

Products or semi-finished products featuring tailored properties are highly relevant for many industrial applications. Hence, new technologies that allow to locally adapt mechanical properties are of key interest. For ...

Residual stresses can cause part distortion especially in the case of large components such as structural parts in aerospace industry. Therefore, this paper investigates the machining induced residual stresses for milling ...

To realize a dry sheet metal forming process, α-Fe 2 O 3 oxide layers were investigated regarding their friction characteristics, wear behavior and surface energy depending on different surface qualities of the specimens ...
