As the needs for the nuclear energy industry continue to evolve in the 21 st century, timely
adoption of new technological solutions acceptable to regulatory agencies is critical …

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

A crystal plasticity modeling framework is developed and used in combination with
experiments for studying the deformation behavior of a polycrystalline Ni-based superalloy …

In part 1, we formally defined important physical concepts in statistical thermodynamics that
undergird internal state variable (ISV) theory such as configurational subsystems (eg …

Additive manufacturing (AM) can create net or near-net-shaped components while
simultaneously building the material microstructure, therefore closely coupling forming the …

Using metal additive manufacturing processes can make up for traditional forging
technologies when forming complex-shaped parts. At the same time, metal additive …

The electrically assisted forming (EAF) technology can reduce the load & stress and improve
the formability of difficult-to-deform alloys due to its coupled thermal and athermal effects. To …

A physically‐based constitutive modeling framework is proposed for the cyclic deformation
and softening of Ni‐based superalloys. The constitutive model accounts for underlying …

In this study, two state-of-the-art implementations of the rate-dependent Crystal Plasticity
Finite Element Method (CPFEM) as user material subroutines in the finite element solvers …

Cyclic deformation of polycrystalline Ni-based superalloys leads to cyclic hardening
followed by softening, in terms of the mechanical response. A micromechanical constitutive …
