Elastic analysis of uniform pressurized axisymmetric cylindrical shells made of saturated porous materials

Abstract

In this present research, for the first time, the elastic analysis of uniform pressurized axisymmetric cylindrical shells made of saturated porous materials is studied. Biot constitutive equations have been utilized to describe the mechanical properties instead of Hook constitutive equations. The governing equations have been formulated via first-order shear deformation theory (FSDT) and virtual work principle. Then, the respective equations have been solved using eigenvalue–eigenvector method for clamped–clamped boundary conditions. The effects of various parameters such as, porosity and Skempton coefficients on displacements and stresses of the cylindrical shells have been investigated. Results indicate that by increasing the porosity coefficient, radial displacement is increased, whereas by increasing the Skempton coefficient, radial displacement is decreased.
