To reduce greenhouse gas emissions and energy consumption of vehicles, among other things, lighter vehicle components are required. One way to achieve this is to construct components where both material, material distribution, and geometry are optimized.
A geometry optimization may lead to components with complex geometries. More and more component tests are made by means of numerical methods, such as the finite element method (FEM). Due to this, efficient and reliable models are desirable. For complex geometries, it may thus be of interest to reduce the computation time by so-called homogenized models. To be able to reduce computation time certain simplifications are required. Due to this, it is important to be aware of which phenomena are of interest and which are not.
In the following a description of the research project LIGHTFe is presented where this is in focus.
The purpose of the project is to develop numerical methods to a computationally efficient way to model and simulate the steel laminate. The laminate should have 30% lower density than the solid steel and meet the requirements of stiffness, impact properties and fatigue placed on the automotive and truck industry.
