Effects of Electric Field and Poling on Fatigue Behavior of PZT Ceramics with Single-Edge Crack by ations. Static and dynamic fatigue tests were conducted on lead zirconate titanate (PZT) ceramics subjected to electric fields, by three-point bending using single-edge precracked-beam technique. A nonlinear finite element analysis (FEA) was also carried out to calculate the energy release rate for

Finite Element Simulation of the Non-remanent Straining Ferroelectric Material Behaviour Based on tl within the framework of a finite element simulation is analysed methodically. Since the specific shape of the polarisation hysteresis is recognised as the principal reason of numerical problems, the considerations given here are limited to the non-remanent straining ferroelectric material model.

Constitutive Behavior of Nano-particle Ferroelectric Ceramics,tric ceramics. In this paper a model is proposed from which the constitutive relation of nanoparticle ferroelectric ceramics is deduced. The model is based on the micro structure of the nanoparticles which consist on the ferroelectric phase and a non-ferroelectric matrix phase. The results show that

An Optimization-Based Computational Model for Polycrystalline Ferroelastics,oelastics is made up of numerous, random oriented grains, with each grain consisting of . types of domains. Under any prescribed loading condition, the fraction of each domain in a specific grain is obtained via an optimization process to minimize the free energy of the total grain. The mechanical c

Modeling of Domain Structure Evolution in Ferroelectric Materials,ure evolution in the vicinity of crack tips. Using the spontaneous polarization as an order parameter the model is set up and implemented into a 2D finite element method. To evaluate crack driving forces the theory of configurational forces is extended to the phase field continuum and numerically re

Micromechanical Simulation of Ferroelectric Domain Switching at Cracks,Each Gaussian integration point of finite elements is considered as a grain comprising a set of distinct domain variants. It is found that a large scale ferroelectric domain switching zone exists in the vicinity of crack tip even under a small magnitude of electromechanical loading. Linear fracture
