TL;DR: In this article, an efficient and accurate framework for the post-buckling analysis of sandwich structures with elastic-plastic material behaviors is proposed, which is based on the Euler-Bernoulli beam theory and high-order functions.

TL;DR: An efficient and accurate approach to investigate the post-buckling behavior of sandwich structures using a novel one-dimensional layer-wise model using Euler-Bernoulli beam theory in the skins and higher-order kinematics in the core is proposed.

TL;DR: In this article, the authors investigated the effects of kinematics approximation on post-buckling analysis of sandwich structures and proposed a 1D layer-wise model, where the core is approximated by Mac Laurin's polynomial functions, and the skins are modelled by Euler-Bernoulli beam theory.
