Simulation Backward extrusion
The model geometry consists of a rigid die, a rigid punch, and a blank
The blank measures 28*89 mm The blank is constrained along its base in the z-direction and at the axis of symmetry in the r-direction
The punch and the die are fully constrained, with the exception of the prescribed vertical motion of the punch The punch is moved downward 82 mm to form a tube with wall and endcap thicknesses of 7 mm each
The blank is made of aluminum and is modeled as a von Mises elastic-plastic material with isotropic hardening The Young’s modulus is 38 GPa, and the initial yield stress is 27 MPa. The Poisson’s ratio is 0.33; the density is 2672 kg/m3
An adaptive mesh domain is defined that incorporates the entire blank Because of the extremely large distortions expected in the backward extrusion simulation
