Virtual Manufacturing versus Challenges in Lightweight Vehicle Programmes

The paper presents a brief summary of three different R&D projects carried out in collaboration between ESI Group and a number of academic and industrial partners. All projects are directly related to producing…

From Part Design to Part Production - Virtual Hot Forming Engineering Illustrated – Focus Material Modelling

In a press hardening process, significant efforts are necessary to model material behavior and combinations of material in one part, patch work, and die spotting. In this paper, a focus will be put on accurate modeling…

Advancements of Virtual Prototyping in the World of Demanding Regulations

Regulations in safety and fuel efficiency are putting more and more pressure on the Automotive Industry to move towards lightweight solutions. Consequently, innovative research and a 3G engineering approach (gage, grade…

Advancements in tailored hot stamping simulations: cooling channel and distortion analyses

Hot stamped components have been widely used in the automotive industry in the last decade where ultra high strength is required. These parts, however, may not provide sufficient toughness to absorb crash energy.…

Virtual prototyping of lightweight designs made with cold and hot formed tailored solutions

Tailored hot and cold formed solutions are one key to the lightweight construction challenges of the future. Only tailored solutions allow the combination of soft and hard zones for the best possible crash performance…

Numerical simulation of powder metal forming process using the SPH Method

The method of Smoothed Particle Hydrodynamics (SPH) is used for the numerical simulation of compaction of iron powder. The character of SPH allows for accurately tracking relevant material properties within a Lagrangian…
