Abstract

This paper focuses on the mechanical buckling analysis of functionally graded beam with piezoelectric layers under low velocity. Simply supported boundary condition considered at both ends of the beam.Fundamental relations, the equilibrium and stability equations derived using the first-order shear deformation theory (FOST) and the Engesser-Timoshenko beam theory (ETB). The influences of periodic loads, dimensionless geometric parameter, functionally graded index and piezoelectric thickness on the critical buckling load of beam presented. To study the precision and accuracy of the present analysis, a compression carried out with a known data and the finite element package ABAQUSE.
