– The rationale for the introduction of high-performance steels in vehicle structures is about reducing weight while maintaining or improving crash safety. The driving force behind this is mainly to reduce the environmental impact of cars. In order to introduce high performance steels to a greater extent, new models and engineering tools for design and sizing is required, says Rickard Östlund, PhD in Solid Mechanics at Luleå University of Technology.
– The modeling methodology that I present in this thesis can be used to simulate and evaluate the course of the collision in vehicle structures, as part of the product development process for new body components. My results have been achieved through a combination of experimental studies and computer modeling.
