Thermal Buckling of Piezoelectric Composite Beam

Abstract EN

Buckling analysis of laminated composite beams with piezoelectric layers subjected to thermal loading and constant voltage is studied.

The material properties are assumed to be homogeneous in any layer through the beam thickness.

The first-order beam theory and nonlinear strain-displacement relation are used to obtain the governing equations of the composite beam.

The beam is assumed under uniform type of thermal loading and various types of boundary conditions.

For each case of boundary conditions, closed-form solutions are obtained.

The effects of the applied actuator voltage, beam geometry, and boundary conditions on the buckling temperature are investigated.
