Abstract

Using E.I.Grigolyk’s line string hypothesis equations of equilibrium and natural boundary conditions were obtained for variable rigidity shells with rigid compressible aggregate. The solution for the boundary problem described by a system of partial differential equations is based on a Bubnov-Vlasov’s method synthesized with a modified successive approximations method. Computation results are presented.
