Effective thermal expansion and pyroelectric constants for cracked piezoelectric solids

摘要

The Effective thermal expansion and pyroelectric constants of 2D cracked piezoelectric materials are obtained through use of the extended Stroh formalism and analytical solution of a crack embedded in a 2D thermopiezoelectric sheet. In the analysis, the self-cnsistent and Mori-Tanaka methods are used to take account of weakening effect among cracks.
