Resumo

A U-bending process is modeled for the analysis of a 1D blank made of aluminum. Geometry of punch, blank and die, plus blank holders is first set. Material properties of aluminum, leading to constitutive equation for the elasto-plastic behavior is constructed next. Contact pressure and tangential friction are prescribed as initial conditions, in a sequence of steps to prepare for punch action. Principal of virtual work, in incremental form is used to model displacements and configurations of the blank. From this information, stresses, strains, shear and bending are computed to show the evolution of geometry, having in mind failure modes associated with damage of the material.
