Geometrically nonlinear vibration analysis of eccentrically stiffened porous functionally graded annular spherical shell segments
<p dir="ltr">This article investigates nonlinear free vibrations of porous functionally graded (FG) annular spherical shell segments surrounded by elastic medium and reinforced by circumferential stiffeners. Porous FG material contains distributed even and un-even porosities and is m...
