Elastic stability of radially nonhomogeneous rings
Variational theory of elastic stability is applied to problem of in-plane buckling of rings in which elastic constants are step functions of radius, as in sandwich or layer construction; strain energy is described using nonlinear theory of elasticity to provide for effects of ring thickness and nonhomogeneity; design curves for determination of critical pressure for two and three element ring configurations are presented; results of tests using nonhomogeneous specimens composed of nickel, glass fiber-epoxy, and urethane foam are presented.
