Modeling & Simulation (Page 4)

The integrity of joints (“stack-ups”) in vehicle frames is of utmost importance when it comes to safety, dependability, and public confidence in the automotive industry. But with up to a hundred joint variations in a car’s body-in-white, it is difficult to predict joint strength properties without extensive testing. Until now. EWI has developed a rapid...

Weld thermal history, which greatly affects material microstructure especially in the heat affected zone (HAZ), can be difficult to predict accurately. As part of its ICME approach to predicting microstructural behavior in welding steels, EWI employs welding thermal cycle data -- welding parameters, materials chemical composition, joint design, and materials thickness as baseline inputs --...

Integrated computational materials engineering (ICME) principles can be applied to model thermo-mechanical material behavior in joining and additive manufacturing applications. Demonstrations and examples have been presented in several recent EWI publications.* The ICME framework can also offer a solution approach to modeling microstructural response in similar applications. EWI Principal Engineer Michael Eff and Senior Technology...
