Abstract Elastic-plastic stress concentrations in spherical shells subjected to internal pressure are of much significance in the theory of structural components. The paper presents the study of elastic-plastic stress concentrations in orthotropic spherical shells made of composite materials subjected to internal pressure by using Seth’s transition theory. It has been seen that the spherical shell of orthotropic composite material requires higher values of pressure at the inner surface as compared to shell of transversely isotropic material. Keywords: composites, orthotropic materials, transversely isotropic materials, stresses, Seth’s transition theory, spherical shell |
