Abstract

This chapter revisits the exact three-dimensional (3-D) approach to study internal instability in layered media based on the model of a piecewise-homogeneous medium, in which the behaviour of each component of the material is described by the 3-D equations of solid mechanics. The results of this approach can be used as a benchmark for simplified models. The chapter begins with the development of a unified computational procedure for numerical realisation of the 3-D analytical method as applied to various constitutive equations of the layers, different loading schemes (uniaxial or biaxial loading) and different precritical conditions (large or small precritical deformations). It contains many examples of calculation of critical stresses/strains for particular composites as well as analyses of different buckling modes. The second part of the chapter deals with the application of a developed model to investigation of compressive behaviour of stiffened thin-skinned composite panels with stress concentrators.
