VOCE CONSTANTS 2

What are the Voce constants?
Our FEA guy also uses Ansys, He always needs to know Young's modulus (modulus of Elasticity), 29000KSI (or thereabouts IIRC, Ultimate Tensile strength, 65-90KSI (depending on form and processing), You said you have yeild stress, the only other one (physicla property) I have easily is %elongation at break, 30-40.
Hope this helps

Voce constants are part of an equation that relates material strengthening vs. accumulated strain. The information required includes critically-resolved shear stress, strain hardening rate, and accumulated strain. It is being used with the Viscoplastic Self-Consistent Model for metal deformation. Information on this subject would be limited to reviewed journals such as Metallurgical and Materials Transactions A and Materials Science and Engineering A. I recommend you search for this information at Scirus:

Just wondering if you guys found any information on this data type? I am running some non linear stuff and I cant find any voce constants for particular metals.
