Gradient-Enhanced Plasticity Theory for Size Effects and Mesh-Independent Numerical Results

초록

In this work, a thermodynamically consistent constitutive formulation for the coupled thermomechanical strain gradient plasticity theory is developed in the context of the finite deformation framework. A corresponding finite element solution is presented to investigate the micro-structural features of metallic volumes. Size effects and mesh-sensitivity are simulated using the developed numerical framework to test the feasibility of the proposed gradient-enhanced plasticity theory. © 2024 75th World Foundry Congress, WFC 2024.
