Applying the WKB Method to the Bifurcation of an Everted Spherical Shell Made of Elastic Varga Material

M. Sanjarani Pour and M. Vakilian

Abstract: The WKB method is a powerful tool to obtain solutions for Eigenvalue problems. We apply the WKB method to the bifurcation analysis of everted a spherical shells composed of Varga material. Incompressible cases are considered. The method is degenerate, but we obtain explicit bifurcation criteria and compare with previous numerical approximations.
