Electromechanical Coupling Correction for Piezoelectric Layered Beams

  title={Electromechanical Coupling Correction for Piezoelectric Layered Beams},
  author={Ellad B. Tadmor and G{\'a}bor K{\'o}sa},
This paper deals with the bending of layered piezoelectric beams (multimorphs) subjected to arbitrary electrical and mechanical loading. Weinberg [1] obtaind a closed-form solution to this problem using Euler–Bernoulli beam theory and integrated equilibrium equations. In his analysis, Weinberg assumes that the electric field is constant through the thickness of the piezoelectric layers. This approximation is valid for materials with small electromechanical coupling (EMC) coefficients. In this… CONTINUE READING
