Cracking Analysis of Automobile Part with Bending Deformation

More Information
  • Received Date: April 29, 2010
    Graphical Abstract
    • Abstract
  • The bending deformation of automobile part was analyzed by the finite element simulation method,the influence of bending radius,material properties and thickness size on bending deformation was discussed.Basedon the analysis results,it was one of the reasons for the bending crack,that small bending radius incurred increaseof tensile stress in the part’s outer surface.Therefore,the properties of Q345steel can not meet the requirements tobending of the automobile part.
