The cross-section response of smart beams under electric, magnetic and thermal fields is investigated.

The semi-analytical procedure divides the contributions of the non-homogeneous governing equation into a homogeneous solution, which resorts to computing the de Saint-Venant solution, and a set of particular solutions which describe the beam cross-section behaviors when external electric potential, magnetic potential and boundary temperature are imposed.

Abstract

The cross-section response of smart beams under electric, magnetic and thermal fields is investigated. The method predicts the generalized cross-section stiffness of prismatic smart beams, and allows recovering the three dimensional multiphysics fields variables. The semi-analytical procedure divides the contributions of the non-homogeneous governing equation into a homogeneous solution, which resorts to computing the de Saint-Venant solution, and a set of particular solutions which describe the beam cross-section behaviors when external electric potential, magnetic potential and boundary temperature are imposed. The generalized cross-section stiffness is computed by means of an energy equivalence equation.
