Tangent modulus AISI 4140

Tangent modulus AISI 4140

(OP)
Hi, I'm trying ti find a material curve for AISI 4140 but haven't found it yet. Can someone help me or maybe send me a sample for use in an FEA simulation?

RE: Tangent modulus AISI 4140

Tangent modulus in fea is the slope between yield point and uts/fracture. I asked the similar question before. It is real stress or strain by the way. One common approach is use 10% of E as tangent modulus. It is required only for nonlinear analysis.
