Interplay between Nucleation and Kinetics in Dynamic Twinning
Janel Chua, Vaibhav Agrawal, Noel Walkington +2
In this work, we apply a phase-field modeling framework to elucidate the interplay between nucleation and kinetics in the dynamic evolution of twinning interfaces. The key feature…
Phase-Field Finite Deformation Fracture with an Effective Energy for Regularized Crack Face Contact
Maryam Hakimzadeh, Vaibhav Agrawal, Kaushik Dayal +1
Phase-field models are a leading approach for realistic fracture problems. They treat the crack as a second phase and use gradient terms to smear out the crack faces, enabling the…
Phase-Field Modeling and Peridynamics for Defect Dynamics, and an Augmented Phase-Field Model with Viscous Stresses
Janel Chua, Vaibhav Agrawal, Timothy Breitzman +2
This work begins by applying peridynamics and phase-field modeling to predict 1-d interface motion with inertia in an elastic solid with a non-monotone stress-strain response. In c…
A Dynamic Multiscale Phase-field Model for Structural Transformations and Twinning: Regularized Interfaces with Transparent Prescription of Complex Kinetics and Nucleation
Vaibhav Agrawal, Kaushik Dayal
The motion of microstructural interfaces is important in modeling materials that undergo twinning and structural phase transformations. Continuum models fall into two classes: shar…
