RISPredictive Science and Technology in Mechanics and Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The papers represented in this edition of JEMT were birthed from a workshop entitled “Predictive Science and Technology in Mechanics and Materials” hosted by the Center of Advanced Vehicular ...
A Nonlocal Phenomenological Anisotropic Finite Deformation Plasticity Model Accounting for Dislocation Defects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A phenomenological, polycrystalline version of a nonlocal crystal plasticity model is formulated. The presence of geometrically necessary dislocations (GNDs) at, or near, grain boundaries is modeled ...
Using Damage Delocalization to Model Localization Phenomena in Bammann-Chiesa-Johnson Metals
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Bammann, Chiesa, and Johnson (BCJ) material model predicts unlimited localization of strain and damage, resulting in a zero dissipation energy at failure. This difficulty resolves when the ...
