Modification of a Constitutive Model for Gassy Clay
Gassy clays containing large, discrete gas bubbles are widely spread in deposits in shallow waters. The existence of gas bubbles may impair the original soil structure, resulting in the instability of offshore foundations and the occurrence of submarine ...

Phenomenological Modeling of Deformation-Induced Anisotropic Hardening Behaviors: A Review
Numerous studies indicate that the hardening behaviors of materials are closely related to their deformation history. In the forming processes with loading path changes, such as sheet metal forming, anisotropic hardening behaviors are universally ...

Regularized Yield Surfaces for Crystal Plasticity of Metals
The rate-independent Schmid assumption for a metal crystal results in a yield surface that is faceted with sharp corners. Regularized yield surfaces round off the corners and can be convenient in computational implementations.

Effects of Unloading on Subsequent Yielding Behavior in 304 Stainless Steel
Forming operations are known to be complex, involving many strain states, strain rates, temperatures, strain paths, and friction conditions. Material properties, such as strength and ductility, are large drivers in determining if a material can be formed
