Finite Element Simulation of Residual Stresses in Roller Bent Section

Residual stresses in a material can be merit or demerit based on service loads. To avoid underestimation or overestimation of strength. Curved C section beams used for a variety of structural application is produced by pyramid roller bending process inducing residual stress in the material. Finite element simulation of pyramid roller bending process with C section beam is been carried out using Abaqus/Explicit analysis. This avoids convergence difficulties in numerical simulations done in static analysis. The technique incorporates contact bending, material non-linearity and geometrical non-linearity.
