I need help in this shape optimization

The peace that i'm doing as this specifications:

  • Material : Aluminium7075-0
  • thickness range (initial 50 mm): 25 – 50 mm
  • Range of the variaton of the radius of the rounding (initial 10 mm): 10 -20 mm
  • Shape optimization: Mass Minimization
  • Restraint 1 – Max Von Mises tension 45 MPa (Security Factor. 2,0)
  • Restraint 2–Max Displassment 0,8 mm

Can someone Help ? I need to optimize this ^
