Stresses in a Shallow Spherical Shell Loaded by Two Tangential Forces Via Rigid Circular Inclusions

We obtain the analytic solution of the problem of stressed state for an isotropic shallow spherical shell with two circular perfectly rigid inclusions loaded by shear forces. The cases of two inclusions of equal or unequal radii are investigated numerically. It is shown that the stresses acting in the shell significantly increase as the radii of the inclusions or the distance between them decrease.
