Relations between fracture toughness and microstructural details have been calculated for ductile materials based on a dilatational plasticity constitutive model that has recently been proposed.
The first one is based on a refined fracture-based plasticity model which requires a numerical solution approach; the second one assumes a simplified bilinear relationship and can be handled analytically.
Here, an original computational averaging scheme is developed for predicting the elastoplastic response of TRIP aided multiphase steels based on a strain gradient plasticity model.
The derivation is based on a strain gradient plasticity solution for an internally pressurized thick-walled spherical shell of an elastic power-law hardening material.
The numerical results agree well with in situ monitoring records of dam settlements, indicating that a three-dimensional finite element procedure based on a modified generalized plasticity model and a hyperbolic interface model can be used to evaluate the deformation of CFRDs.
The pattern storage phase is based on a spike timing dependent plasticity (STDP) rule and the pattern association phase is compatible with the classic Hebbian rule.
Prediction of the effects of length-scale on fretting crack initiation is based on a three-dimensional, crystal plasticity, frictional contact model to predict fretting crack location and initial growth path, accounting for the effects of crystallographic orientation.
Simulations are based on a microstructure-sensitive crystal plasticity model to quantify fatigue indicator parameters (FIPs) at the slip system level and a fatigue model that relates FIPs to fatigue lives of individual grains.
Non-ordinary state-based peridynamics and the Newmark's dynamic method with artificial damping are employed to capture strain localizations in polycrystalline microstructures based on a rate-independent crystal plasticity model.
