Abstract
The paper deals with the stress distribution around cavities under pressure in an infinite, non-linear elastic material. A homogeneous stress state is assumed at infinity. For spherical and cylindrical cavities simple formulae are derived for the stress concentration, the extent of the non-linear zone and the volume reduction. Results are given for cavities in rock salt, and a comparison with measured stress concentrations is used to support the assumption of a hydrostatic stress state in undisturbed salt formations. Finally a method to estimate convergence due to creep is outlined.
