Deep drawing is a forming process in which a blank of sheet metal is drawn into a die by a moving punch. The blank is clamped by a blank holder against the die. The deep drawing process takes place slowly such that inertial effects are negligible and it can be termed as quasi-static. Quasi-static problems can be simulated well with either Abaqus/Standard or Abaqus/Explicit. Typically, quasi static problems are solved with Abaqus/Standard but may face convergence difficulties due to contact or other nonlinearities. Such problems are a good candidate to be solved with Abaqus/Explicit as explicit procedure can resolve complicated contact problems and other discontinuous nonlinearities more easily than Abaqus/Standard. Significant changes in the thickness of blank take place during deep drawing which is of interest to designers.
This is a challenging problems as it involves multiple nonlinearities: material nonlinearity, geometric nonlinearity and contact between multiple components. By taking advantage of the symmetry, only a quarter of the blank will be considered for simulation.
Note: This exercise is part of the Solving Non-linear Problems with Abaqus course.
