A Cosserat crystal plasticity and phase field theory for grain boundary migration
Anna Ask, Samuel Forest, Benoit Appolaire +2
The microstructure evolution due to thermomechanical treatment of metals can largely be described by viscoplastic deformation, nucleation and grain growth. These processes take pla…
A Sharp Phase Field Method
Alphonse Finel, Yann Le Bouar, Benoît Dabas +1
Phase field modelling offers an extremely general framework to predict microstructural evolutions in complex systems. However, its computational implementation requires a discretis…
Fracture initiation in multi-phase materials: a systematic three-dimensional approach using a FFT-based solver
T. W. J. de Geus, M. Cottura, B. Appolaire +2
This paper studies a two-phase material with a microstructure composed of a hard brittle reinforcement phase embedded in a soft ductile matrix. It addresses the full three-dimensio…
Density-based crystal plasticity : from the discrete to the continuum
P. L. Valdenaire, Y. Le Bouar, B. Appolaire +1
Because of the enormous range of time and space scales involved in dislocation dynamics, plastic modeling at macroscale requires a continuous formulation. In this paper, we present…
