Control
Adaptive 1
This problem includes three tools a punch, a binder and a die and also includes a blank to be formed. The blank is deep drawn by the punch while the binder and die hold the blank edges and help prevent wrinkling. During the process, adaptivity is employed to refine the mesh of the blank to improve accuracy.
Adaptive 2
A square cross section of a crush tube uses adaptivity to re-fine the mesh as needed to improve accuracy.
Adaptive 3
Several nodes on a cylinder are given initial velocities towards the center of the cylinder causing the cylinder to indent. To improve accuracy, adaptivity is defined so that the mesh of the cylinder is re-fined during the deformation.
Contact
This problem includes three tools a punch, a pressure pad, a die and a workpiece. A workpiece is deep drawn by the hemispherical punch while the pressure pad and die prevents wrinkling. The load on the pressure pad is ramped, then the punch displaces in the y direction.
Damping
A cantilever beam is subjected to a load at the free end. The beam then vibrates relative to the equilibrium position without damping in case 1 and with damping in case 2.
Energy
A copper bar strikes a wall.
Shell 1
A spherical shell is subjected to outward point loads on the x-axis and inward point loads on the z-axis.
Shell 2
A beam twisted 90 degrees about its length is constrained on on e edge and has a point load prescribed normal to the opposite end of the beam.
Timestep
A rod of steel is forged between two dies. The billet upset problem is a measure of friction under forming conditions.
