Elastoplastic hardening laws (Simcenter Samcef)

You can define elastoplastic hardening laws in a Samcef Isotropic Structure, in a Samcef Orthotropic Structure, or in a Samcef Anistropic Structure material, on the Mechanical page of the materials dialog box.

You can define a full Kinematic hardening law or a Mixed Hardening one.

Kinematic hardening law

To define a kinematic hardening law, from the Hardening Rule (HR) list, select Kinematic.

From the Kinematic Laws list, you can then choose between a Prager (KPRA) law or a Ziegler (KZIE) one.

Then you define the Non-Linear Hardening Coefficient (NLH) property.

Mixed hardening law

To define a mixed hardening law, from the Hardening Rule (HR) list, select Mixed Hardening.

From the Kinematic Laws list, you can then choose between a Prager (Kpra) law or the Ziegler (KZIE) one, and you define its related Non-Linear Hardening Coefficient (NLH) property.

With the Hardening Ratio, you can balance the hardening law between the standard Isotropic formulation and the full Kinematic one.

For more information, see the elastoplastic behavior page in the Simcenter Samcef solver documentation.
