Second-Order Two-Scale Asymptotic Expansions for Thermopiezoelectric Problems in Periodic Structure

Abstract:

In this paper, we construct a second-order two-scale (SOTS) asymptotic expansions for thermopiezoelectric problems in periodic structure by means of construction way. A set of numerical results are demonstrated for predicting the temperature, mechanical displacement and electric potential in periodic structures. It shows that SOTS's asymptotic expansions can capture the 3-D local behaviors caused by 3-D micro-structures well.
