Abstract
Drivers safety is a high-priority task for engineers. One way to ensure this is to increase vehicles passive safety. Another way to improve road safety is to improve road fences design. This article is concerned with the issues of finite element (FE) modeling a vehicle collision with road fences using the LS-DYNA software package. The article presents a number of problems for modeling a vehicle with an oblique impact in a road fence, in particular, the friction issues between the vehicle tires and the road, the car friction elements and the road fence, problems of describing large deformations and fracture of parts with large FEM meshes and interactions with elements in a small overlap area.
