Neuroplasticity … WebJan 5, 2024 · A non-local gradient-enhanced damage-plasticity formulation is proposed, which prevents the loss of well-posedness of the governing field equations in the post-critical damage regime. The non-locality of the formulation then manifests itself in terms of a non-local free energy contribution that penalizes the occurrence of damage gradients.
WebIn order to reflect nonlinearity, the bi-scalar damage plasticity constitutive model is proposed, in which the effective stress is split into positive and negative parts. The scalar tension and compression damage variables are introduced, and the rate-dependent damage evolution process is established with the help of Stefan effect.
