A combined experimental and strain gradient crystal plasticity framework is presented for
studying the development of orientation and misorientation gradients at the grain …

Abstract Recurrent Neural Network (RNN) based surrogate models constitute an emerging
class of reduced order models of history-dependent material behavior. Recently, the authors …

Microstructure-based models of additive manufactured (AM) Ti-6Al-4V should faithfully
represent the unique microstructural features of these materials to provide a more thorough …

The Chaboche isotropic-kinematic hardening (CIKH) model provides a versatile and realistic
description of the material stress–strain behavior under generic multiaxial cyclic loadings …

Additively manufactured (AM) materials are prone to porosity, which limits their widespread
adoption in fatigue-limited applications. Experimental campaigns are vital in understanding …

A dislocation density based crystal plasticity model is developed to account for the
precipitate induced cyclic softening in IN718. The new model treats the interaction between …

The PRISMS-Fatigue open-source framework for simulation-based analysis of
microstructural influences on fatigue resistance for polycrystalline metals and alloys is …

We propose a mechanics framework to compute intragranular or type III residual stress
within a polycrystalline aggregate for which experimental characterization of residual stress …

For crystal plasticity formulation neglecting the strain gradients at the dislocation scale,
backstresses are necessary to satisfy the mesoscopic stress equilibrium and strain …

The intergranular stress was investigated at grain boundaries (GBs) of Ti-2Al-2.5 Zr alloy
under cyclic loading. The crystal plasticity (CP) simulations revealed that the strain …
