Process Chaining Approach With Simulation: From Cast Ingot To Final Properties Of Forged Component

The aim of this study is to evaluate, through FEM software simulation, the quality and properties that can be achieved on a forged component, taking into account results of casting process used to produce ingot . In…

Integration of Coupled Casting and Structure Simulation for Magnesium Die Castings

Simulation is an important tool in the different phases during development. It is used in the early, purely virtual development phase as well as in later production and final test phases, respectively, to analyse and…

Lifetime Extension of Ingot Casting Molds

Due to high thermal loads subjected on the mold during casting process, cracks appear after a limited number of casting cycles. This article provides an overview of influence factors, as well as measures to increase the…

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…

Effects of Manufacturing Process in Crash Simulations

This article describes an impact of a manufacturing, which can significantly change real parts behavior. The influence of technology process is neglected in regular simulations. However, advanced finite elements solvers…

Aero Forming - An Introduction of Collaborative Engineering

The decrease of physical prototypes and the growing power of simulation in the design process require greater control in the design chain calculation. This is the main reason for the arrival of SDM in the perimeter of…

Collaborative development of finite element models for Honeycomb crash test barriers: Crash / Volkswagen

Deformable barriers used in car crash testing are based on aluminium honeycomb blocks covered by aluminium plates. These structures, that largely deform and tear during crash tests, represent a challenge for the…

Enhancements and validation of FPM fluid structure interaction module applied to curtain airbag deployment

Models to represent in position situations based upon uniform pressure assumptions are well established and have been used extensively in the automotive industry for more than 15 years. More recently, in the beginning…

Violent Flow using a fully coupled SPH-HE approach

Designing structures located either off-shore or on-shore, able to withstand loads coming from large impacting waves or for entering water poses a major technological challenge. Virtual prototyping using advanced…

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…
