Using a Timoshenko beam approach, a system of nonlinear differential and integral equations is derived that predicts critical and secondary instabilities. These are validated against numerical simulations performed within the commercial finite-element package Abaqus. Good agreement is found, and this offers encouragement for more elaborate models to be devised that can account for face-core delamination—a feature where functionally graded materials are known to offer distinct advantages.||URI:||http://ktisis.cut.ac.cy/handle/10488/4967||ISSN:||1943-7889||DOI:||10.1061/(ASCE)EM.1943-7889.0000470||Rights:||© American Society of Civil Engineers||Type:||Article|
