Three–dimensional Stability Loss Problems Of Local Near-surface Buckling Of A System Consisting Of An Elastıc Bond Layer And An Elastic Covering Layer

Abstract

Within the framework of a piecewise homogenous body model and by the use of a threedimensional linearized theory of stability (TLTS), the local near-surface buckling of a material system consisting of a half-space which is covered by the single layer and halfspace materials is elastic. The equations of TLTS are obtained from the three-dimensional geometrically nonlinear equations of the theory of viscoelasticity by using the boundary form perturbations technique. By employing the Laplace and Fourier transform, a method for solving the problem is developed. Numerical results on the critical compressive forces and the critical times are presented.Buckling instability, curved-layer, critical time, local near-surface buckling, stability, viscoelastic layer
