VIBRATIONS OF A SHALLOW SPHERICAL-SHELL ON A KERR FOUNDATION

Large amplitude free vibrations of a cramped shallow spherical shell o n a Kerr-type elastic foundation model are investigated. A detailed pa rametric study is conducted involving geometric and elastic properties of the shell as well as representative foundation parameters. Influen ce of these variables on the relation between the nondimensional frequ ency and amplitude are discussed. Shells with immovably clamped edges are more vulnerable to the changes in the above-referred parameters th an those with movable clamped edges.
