Composite failure criteria usage in metal?

Composite failure criteria usage in metal?

(OP)
Hi all,

I would like to use Tsai-Hill 3D transversely isotropic failure criterion in modeling metal. The failure model requires 3 parameters -The axial (X) and in-plane (Y) tensile strengths and the transverse shear strength (S). To be valid, the parameters X and Y must satisfy the relation: Y < 2X. Note that I only have uni-axial tensile data.

Can I use the same tensile strengths for X and Y since metal is isotropic in all directions? If yes, then how do I calculate the S from uni-axial tensile data?

RE: Composite failure criteria usage in metal?

Why in tarnation would you want to use for metal analysis a failure criteria that does not work for composites? Just use von mises or max principal stress as appropriate for the type of material.
