Radial Deformations and Cavitation on Riemannian Manifolds with Applications to Nonlinear Membrane Shells
摘要
This study is a geometric version of Ball’s work (Philos Trans R Soc Lond Ser A 306(1496):557–611, 1982). Radial deformations in Riemannian manifolds are singular solutions to some nonlinear equations given by constitutive functions and radial curvatures. A geodesic spherical cavity forms at the center of a geodesic ball in tension by means of given surface tractions or displacements. The existence of such solutions depends on the growth properties of the constitutive functions and the radial curvatures.
