Abstract: The attempt to satisfy subsidiary conditions in boundary value problems without additional independent unknowns in the form of Lagrange multipliers has led to the development of so-called “simplified ...

Abstract: The governing differential equations and the virtual work expressions for the large displacement analysis of thin arches of arbitrary shape, subjected to pressure loads, are derived. The virtual ...

Abstract: Consideration of the dependence of hydrostatic pressure on the displacements may result in significant changes of calculated buckling loads of thin arches and shells in comparison with loads ...

Abstract: Concepts involving direct approaches for continuum structural reanalysis of modified shapes employing the boundary‐element analysis (BEA) method are considered. A boundary‐element zone‐condensation technique is shown to ...

Abstract: The elastic instability of an internally-pressurized cylindrical tank with a torispherical head is investigated using a triangular, doubly curved, thin-shell finite element. The formulation of the ...
