PURPOSE:Vertebral fragility fractures are often treated by injecting bone cement into the collapsed vertebral bodies (vertebroplasty). The mechanisms by which vertebroplasty induces pain relief are not completely understood yet and recent debates cas

AlSi coating fracture during press hardening of boron steel can significantly increase tool wear and reduce the product quality. During heating of AlSi-coated press hardening steel, the coating layer evolves due to diffusion. This results in various

Sheet metal surfaces are generally textured to improve tribological performance in deep drawing applications. Variations in coefficient of friction in forming processes is one of the major causes of defective products. The major reasons for an unstab

The accurate description of friction is critical in the finite element (FE) simulation of the sheet metal forming process. Usually, friction is oversimplified through the use of a constant Coulomb friction coefficient. In this study, the application

In the stamping of industrial parts, friction and lubrication play a key role in achieving high quality products and reducing scrap. Especially in the start-up phase of new production runs, transient effects can have a significant impact on the produ

It is widely realized in the metal forming industry that the processes suffer from start-up effects, which can cause products that fall out of their specification limits after a certain period of running. Attempts are made to solve this by modelling

For industrial hot stamping applications, press hardening steel is usually coated with Al-10wt.%Si, in order to prevent substrate decarburization and oxidation at elevated temperatures. However, during hot stamping, the AlSi coating layer fractures,

Accurate modeling of friction is important in Finite element (FE) analyses of forming processes. Friction behavior depends on various parameters such as local contact load, surface topographies of sheet metal and tool, their material properties and t

Hot stamping is used to produce structural automotive parts. In this process, high strength ( 1500 MPa) can be achieved with good formability and accurate geometrical tolerances due to the combination of a forming step at high temperature ( 700 °C)
