Stress State of Non-Thin Elliptical Cylindrical Shells Under a Local Longitudinal Load

The spatial problem of the stress state of non-thin elliptical cylindrical shells is solved using the analytical methods of separation of variables, approximation of functions by discrete Fourier series, and the numerical method of discrete orthogonalization. The shells are made of isotropic and orthotropic materials and acted upon by a local longitudinal load. The results obtained are presented in the form of plots and tables of fields of displacements and stresses.
