Synopsis:

Kinds of thin-walled structures, idealization, geometry and loading. St.Venant´s principle. Theory and relations for thin shells, boundary conditions, stress and deformation response to loading. Cylindrical, conical, spherical and anuloid form of shell, their joints. Thermal stresses, stability. Practical application, storage tanks, pressure vessels, pipe lines, elbow, T branch.
