# Wrinkling predictions in a deep drawing test (Tutorial)

Aabqus tutorial - deep drawing

The material used in our deep drawing analysis is steel with isotropic behavior. The initial position of the punch is taken as 10mm above the sheet. The Deep drawing speed used here is 1 m/sec. The friction between the sheet, the punch and die interface is taken constant as 0.15.

The young modulus E is taken equal to 210GPa and the poisson’s ratio v =0.3. The density is equal to 7800kg/m2.

A mass of 5 kg is attached to the blank holder, and a concentrated load of 10 kN, is applied to the contact surface blank/ holder, the blank holder is then allowed to move only in the vertical direction.

Based on the symmetry boundary conditions, only a quarter of the geometry is modeled
