Deformations of an elastic half plane with a circular cavity. (English) Zbl 0918.73014
Summary: An analytical solution is given of the class of problems of an elastic half plane with a circular cavity, loaded on the cavity boundary. The solution uses complex variables, with a conformal mapping onto a circular ring. The coefficients in the Laurent series expansions of the stress functions can be expressed through a single constant by a system of recurrent relations, obtained from the boundary conditions. The remaining constant can be determined from the requirement of convergence of the series. For the case of a uniform radial stress at the cavity boundary, the solution can be given in closed form, confirming known results for the stresses, but also giving simple explicit expressions for the displacements.
