    This paper incorporates an analysis of the stability of orthotropic or isotropic cylindrical shells subjected to external pressure applied over all or part of their surfaces. An eighth-order governing equation for buckling of orthotropic, isotropic, and composite cylindrical shells is by: 1. This paper deals with the nonaxisymmetric dynamic behavior of fluid‐filled buried orthotropic cylindrical shells/pipes excited by plane longitudinal waves. A thick shell model including the effects of shear deformation and rotary inertia is taken. A perfect bond between the shell and the surrounding soil is assumed.

      Presenting recent principles of thin plate and shell theories, this book emphasizes novel analytical and numerical methods for solving linear and nonlinear plate and shell dilemmas, new theories for the design and analysis of thin plate-shell structures, and real-world numerical solutions, mechanics, and plate and shell models for engineering appli5/5(4). of axisymmetric dynamic loading of multilayer orthotropic shells, taking into account geometrical and physical non-linearity, then to analyze the influence of various reinforcement schemes and types of non-linearity on the stress-strain state of thick-walled cylindrical shells subjected to axisymmetric impulsive action. 2.
