Abstract

We develop a phenomenological model of electro-mechanical ferroelectric fatigue based on a ferroelectric cohesive law that couples mechanical displacement and electric-potential discontinuity [...]

Abstract

We propose a phase-field model for the coupled simulation of microstructure formation and evolution, and the nucleation and propagation of cracks in single-crystal ferroelectric materials. [...]

Abstract

We present a phase-field model to simulate intergranular and transgranular crack propagation in ferroelectric polycrystals. The proposed model couples [...]

Abstract

We simulate the fracture processes of ferroelectric polycrystals in three dimensions using a phase-field model. In this model, the grain boundaries, cracks and ferroelectric domain walls [...]

Abstract

We present a family of phase-field models for fracture in piezoelectric and ferroelectric materials. These models couple a variational formulation [...]

Abstract

Ferroelectric ceramics are susceptible to fracture under high electric fields, which are commonly generated in the vicinity of electrodes or conducting layers. In the present work, we extend [...]

This paper presents a family of phase-field models for the coupled simulation of the microstructure formation and evolution, and the nucleation and [...]
