RISDiscussion: “An Inelastic Constitutive Model for Monotonic, Cyclic, and Creep Deformation: Part I—Equations Development and Analytical Procedures and Part II—Application to Type 304 Stainless Steel” (Miller, A., 1976, ASME J. Eng. Mater. Technol., 98, pp. 97–105, 106–112)
Publisher: The American Society of Mechanical Engineers (ASME)
Viscoplasticity Based on Total Strain. The Modelling of Creep With Special Considerations of Initial Strain and Aging
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A previously proposed theory is specialized for the uniaxial state of stress and its prediction for creep and relaxation is analyzed in detail. Constant true stress and constant load creep ...
Modeling of High Homologous Temperature Deformation Behavior Using the Viscoplasticity Theory Based on Overstress (VBO): Part II—Characteristics of the VBO Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Characteristics of the high homologous temperature VBO model under extreme conditions such as very fast and very slow tensile tests, long-term-creep and relaxation tests are investigated via ...
The Modeling of Unusual Rate Sensitivities Inside and Outside the Dynamic Strain Aging Regime
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The viscoplasticity theory based on overstress (VBO) is altered by introducing an augmentation function into the dynamic recovery term of the growth law of the equilibrium stress, which is a ...
Modeling of High Homologous Temperature Deformation Behaviour Using the Viscoplasticity Theory Based on Overstress (VBO): Part III—A Simplified Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simplified version of the Viscoplasticity Theory Based on Overstress (VBO) is applied to modeling of Alloy 800H at homologous temperatures between 0.6 and 0.8 The present formulation is ...
Modeling of High Homologous Temperature Deformation Behavior Using the Viscoplasticity Theory Based on Overstress (VBO): Part I— Creep and Tensile Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The viscoplasticity theory based on overstress (VBO) is a state variable theory without a yield surface and without loading/unloading conditions. It contains two tensor valued state variables, ...
Amorphous and Semicrystalline Solid Polymers: Experimental and Modeling Studies of Their Inelastic Deformation Behaviors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The study of the inelastic deformation behavior of six amorphous and semicrystalline polymers was performed to develop and verify the capabilities of a constitutive material model. The test ...
