RISA Modeling Investigation of Thermal and Strain Induced Recovery and Nonlinear Hardening in Potential Based Viscoplasticity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Specific forms for both the Gibb’s and the complementary dissipation potentials were chosen such that a complete potential based multiaxial, isothermal, viscoplastic model was obtained. This model, ...
Effective Strategy for Automated Characterization in Complex Viscoelastoplastic and Damage Modeling for Isotropic/Anisotropic Aerospace Materials
Publisher: American Society of Civil Engineers
Abstract: The development of an overall strategy to estimate the material parameters for a class of recent viscoplastic and damage-material models is presented. The procedure is automated through an integrated parameter estimation ...
