Abstract The task of determining the dynamic response plates and shells to moving loads is very relevant. purpose this work study stationary deformation infinitely long cylindrical with viscoelastic filler when along axis shell a wave normal pressure up resonant velocity under influence loads. paper presents mathematical formulation problem, developed methods solution obtained numerical results...

Abstract One of the basic load cases relevant for design shell structures is torsion, which can occur exemplary in silos and tanks under seismic actions or even wind loading. To address stability problem cylindrical shells this case, standard EN 1993‐1‐6 European Recommendation ECCS EDR5 provide simple approaches buckling shells. In order to improve current hand calculation rules given above do...

We develop maximum principles for several P functions which are defined on solutions to equations of fourth and sixth order (including a equation which arises in plate theory and bending of cylindrical shells). As a consequence, we obtain uniqueness results for fourth and sixth order boundary value problems in arbitrary n dimensional domains.
