BUCKLING OF DISCRETELY RING STIFFENED CYLINDRICAL SHELLS

摘要: Abstract : The buckling of ring-stiffened cylinders is studied by a 'discrete' approach, in which the rings are considered as linear discontinuities represented Dirac delta function. analysis Donnell type theory that takes account eccentricity stiffeners. Buckling loads under hydrostatic pressure, lateral pressure and axial compression compared with those obtained 'smeared-stiffener' for an extensive range geometries. discreteness effect depends very strongly on geometry shell rings. Significant effects found loading.
