I need to define mechanical properties of 409 Stainless steel for FEA. The following I obtain from Matweb.com and other sources:
density = 7.8 g/cm^3
Youngs = 200 GPa
Poisson = 0.28
Yield = 240 MPa
Ultimate = 450 MPa
Can anyone suggest an appropriate value for the strain hardening exponent, n, in Hookes Law of non-linear(plastic) material deformation?
(stress = K * strain^n)
Also, I need to be able to define Lankford plastic strain ratios (r00, r45, r90). We can assume homogeneous material, so I can substitute the average, r-bar, for each of these, if I can find it...
If anyone can suggest appropriate values (or better yet, a resource that I can continue to use) I would appreciate it.
