DEFORMATIONS IN AN INFINITE CYLINDRICAL-SHELL RESTRAINED BY ELASTIC OR RIGID WALLS

The contact problem of an infinite cylindrical shell with an elastic or a rigid foundation is investigated. A shear deformation non-linear shell theory is used in setting up the governing differential equations and the functional of total potential energy. The variations of contact pressure and domains are discussed for different shell parameters, friction and rigidity coefficients of foundation. The obtained results are compared with the results for geometrically linear shell theory. Some problems connected with the variational inequality formulation of the analyzed unilateral boundary problem are also discussed.
