“Analysis of buckling and wrinkling of plate under thermo-mechanical loading using a Fourier-related multi-scale approach”, The 6th International Conference on Coupled Instabilities in Metal Structures, December 2012, http://www.researchgate.net/publication/275580848
ABSTRACT: In this paper, we study the temperature’s effect on a plate under global tensile stress. For this aim, the Fourier double scale method is used in order to develop a macroscopic model that is a generalized continuum. This model couples local and global instabilities in wrinkling phenomena. The advantage of this technique is to remain valid away from the bifurcation point while former techniques such as Landau-Ginzburg theory are valid only close to the bifurcation point. Due to its efficiency, this method is extended to plate structures. A finite element formulation of the plate model is made. The model developed was implemented using MATLAB code and a validation test has been conducted, comparing to ABAQUS simulation.
