Essay

The work presents the research of Stress state near the circular holes in the non-thin transversally isotropic elastic and electro-elastic plates and the hollow spherical shells. In the founding of solution as a there was put the method is constructed of expansion of the needed functions in to Fourie’s series in Legendre’s polynomials coordinate of thickness. According to the coefficients of the expansion as the functions of two independent variables is given the system of differential aquations and corresponding boundary conditions. On this basis there was found the solutions of boundary problems about the stressing state near the circular holes. The appropriateness of stress distribution near the hole depending on geometry parameters, stressing and piezoelectric properties of the materials were exposure on the specific examples.
