The article considers the elastic properties calculation method (compliance coefficients)
of continuous elastic foundation, which is the link between the inner and outer cylindrical
shells forming the composite shell. The method takes into account the two shells geometry
and the physical-mechanical properties of the elastic foundation material. The method
described presents the plane problem of the elasticity theory as a system with the finite
number of degrees of freedom in the transverse direction, while maintaining the infinite
number of degrees of freedom in the longitudinal direction.
Keywords: composite shell, inner shell, outer shell, continuous elastic foundation, gener-
alized model, single-layer model, displacement method, equilibrium condition, compli-
ance factor.
