It is based on the use of complex potentials, conformal mappings and the least squares method. A series of problems is solved and detailed numerical researches of stresses, density of potential energy distributions and changes of stress intensity factors (SIF) for plane concentrators are carried out. A series of new mechanical regularities is obtained. Analytical expressions for stresses in transversal-isotropic spherical membrane with a circular hole or absolutely rigid inclusion under action of even pressure with use of exact values of McDonald cylindrical functions are received and analyzed. Influence of relative radius of a contour and parameter of a pliability to cross-section slides is analyzed. Product Description popup.authors popup.nrat_date 2020-04-02 Close
