Abstract: A general analysis of cross sections subjected to axial force and biaxial bending is presented. The method is based on Green's theorem and allows for exact determination of stress resultants and tangent stiffnesses for a ...

Abstract: When computational modeling is used to evaluate the true strength of an imperfect elastic-plastic shell structure, the current European standard on shell structures requires that two reference ...

Abstract: Rings or ringbeams are often used to stiffen cylindrical tanks, silos, towers, and pressure vessels. A ring acts together with the axisymmetric shell to form a composite structure. The structural analysis of such a composite ...

Abstract: Small cylindrical pressure vessels are often constructed with a circular flat plate end closure. The end-plate undergoes large deformations under working loads. High local stresses develop at the ...

Abstract: The behavior of thin cylindrical shells under axial compression is very sensitive to imperfections in the initial geometry. Local axisymmetric imperfections are among the most detrimental and have been shown to be a regular ...

Abstract: A detailed nonlinear finite-element analysis is undertaken of the wall pressures exerted by iron ore pellets in a full-scale silo experiment. The ring stiffeners on the exterior of the silo wall cause local small axisymmetric ...

Abstract: The most demanding design situations for silo structures usually occur at the onset of discharge, when the silo is still almost full of granular solid. In this condition, the pattern of solids flow affects the wall pressures, ...
