Integrating Design Portal System

As part of the effort to create the new aero space craft, China Aerospace Science and Technology Corporation (CASC) analysed and optimized their design processes. The INTEGRATING DESIGN PORTAL SYSTEM (IDPS) helps to…

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…

Grain Structure Prediction

The control of grain structure, which develops during solidification processes in investment casting of nozzle guide vanes (NGVs), is a key issue for optimization of their mechanical properties. The main objective of…

Thermal calibration and porosity prediction

Investment casting is the only commercially used technique for fabrication of nozzle guide vanes (NGVs), which are one of the most important structural parts of gas turbines. Manufacturing of NGVs has always been a…

Conversion of a Vacuum-Assist Casting to a Conventionally Vented Casting with Casting Simulation

In the current competitive environment, the capability to produce high quality die casting components whilst reducing production cost and development times is a challenge the foundry industry must face up to. Whether it…

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…

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…
