Dislocations in the elastic fields of randomly distributed defects
Ronghai Wu, Michael Zaiser
In recent years, the behavior of dislocations in random solid solutions has received renewed interest, and several models have been discussed where random alloys are treated as eff…
Continuum Dislocation Dynamics as a Phase Field Theory with Conserved Order Parameters
Yufan Zhang, Ronghai Wu, Michael Zaiser
The dynamics of dislocations can be formulated in terms of the evolution of continuous variables representing dislocation densities ('continuum dislocation dynamics'). We show for…
Phase-field, dislocation based plasticity and damage coupled model: modelling and application to single crystal superalloys
Ronghai Wu, Yufan Zhang
In the present work, we propose a novel model coupling phase-field, dislocation density based plasticity and damage. The dislocation density governing equations are constructed bas…
A modified divide-and-conquer based machine learning method for predicting creep life of superalloys
Ronghai Wu, Lei Zeng, Xing Ai +1
Recently Liu et al. (Acta Mater., 2020) proposed a new divide-and-conquer based machine learning method for predicting creep life of superalloys. The idea is enlightening though, t…
Pinning of dislocations in disordered alloys: Effects of dislocation orientation
Michael Zaiser, Ronghai Wu
The current interest in compositionally complex alloys including so called high entropy alloys has caused renewed interest in the general problem of solute hardening. It has been s…
Thermodynamic considerations on a class of dislocation-based constitutive models
Ronghai Wu, Michael Zaiser
Dislocations are the main carriers of plastic deformation in crystalline materials. Physically based constitutive equations of crystal plasticity typically incorporate dislocation…
