Interactions between a Main Crack and a Micro Crack in a Thermopiezoelectric Plate
نویسنده
چکیده
This paper treats the interactions between a main crack and a rnicrocrack in an anisotropic piezoelectric solid. Based on the Green's function approach and the principle of superposition, a system of singular integral equations for the unknown temperature discontinuity defined on each crack face is developed and can be solved numerically. In the analysis, the residual heat flux, stress and electric displacement on rnicrocrack location to be released are evaluated directly from the near-tip fields of main crack.

BEM for crack-inclusion problems of plane thermopiezoelectric solids
The problem of interactions between an inclusion and multiple cracks in a thermopiezoelectric solid is considered by boundary element method (BEM) in this paper. First of all, a BEM for the crack}inclusion problem is developed by way of potential variational principle, the concept of dislocation, and Green's function. In the BE model, the continuity condition of the interface between inclusion ...
متن کاملPredicting Low Cycle Fatigue Life through Simulation of Crack in Cover Plate Welded Beam to Column Connections
This paper presents a low cycle fatigue life curve by simulating a crack in a cover plate welded moment connection. Initiation of ductile fracture in steel is controlled by growth and coalescence of micro-voids. This research used a numerical method using finite element modeling and simulation of ductile crack initiation by a micromechanical model. Therefore, a finite element model of a cover p...
متن کاملCrack Tip Constraint for Anisotropic Sheet Metal Plate Subjected to Mode-I Fracture
On the ground of manufacturing, sheet metal parts play a key role as they cover about half of the production processes. Sheet metals are commonly obtained from rolling and forming processes which causes misalignment of micro structure resulting obvious anisotropic characteristics and micro cracks. Presence of micro cracks poses serious attention, when stresses at the tip reach to the critical v...
متن کاملThermoelectroelastic Green's function for a piezoelectric plate containing an elliptic hole
Using Stroh's formalism and conformal mapping, Green's functions are obtained in closed-form for an in®nite thermopiezoelectric plate with an elliptic hole induced by temperature discontinuity. The Green's function satis®es freetraction-charge as well as thermal-insulated conditions along the hole boundary. Based on the Green's function, a system of singular integral equations for the unknown t...
متن کاملA boundary element analysis of crack-propagation mechanism of micro-cracks in rock-like specimens under a uniform normal tension
In this work, the mechanism for fracture of brittle substances such as rocks under a uniform normal tension is considered. The oriented straight micro-cracks are mostly created in all the polycrystalline materials resulting from the stress concentrations. The present work focuses on the interactions of the pre-existing micro-cracks, which can grow and propagate within a rock-like specimen. The ...
