Application of A Hybrid WKB-Galerkin Method in Control of Dynamic Instability of Piezolaminated Imperfect Column

Abstract

This paper deals with the problem of dynamic instability of piezolaminated column subjected to arbitrary axial load. The aim of the analysis is to obtain the closed form solution for the equilibrium equation of the loaded column considering variable in time damping coefficient, presented as function of time. Solution of the problem is obtained using A Hybrid WKB-Galerkin method.
