The decision of using computer algebra package based on «Mathematica» plane problem of educa-tion circular cavity in a preloaded infinitely extended body of the non-linear elastic material. Taken into account that the formation of the cavity leads to a redistribution in the solid of finite deformations. The shape of the cavity defined at the moment of its formation. The material properties are described untested relations proposed by various researchers. Statement of the problem is based on the theory of multiple overlay large deformations. An approximate analytical solution and its comparison with known exact solution for a particular case.
