Reinforced vehicle structural part, vehicle and method

摘要

A vehicle structure component reinforced by means of an area, a vehicle comprising such a vehicle structure component, and a corresponding method to reinforce a vehicle structure component are proposed. The area comprises a compressive residual stress in a first direction and a compressive or tensile residual stress in a second direction being vertically aligned to the first direction, wherein the ratio of the compressive stress in the first direction and the compressive or tensile residual stress lies between -0.2 and +1.0. Hence, the propagation direction of cracks in such areas is diverted, faster pressure equalization takes place, and further crack propagation is inhibited.
