В работе представлены экспериментальные результаты деформирования тонкостенного трубчатого образца по гладкой криволинейной траектории деформирования постоянной кривизны, в которой на каждом участке изменяется знак кривизны и смещается ее центр. Экспериментальное исследование выполнено на автоматизированном расчетноэкспериментальном комплексе СН-ЭВМ в девиаторном пространстве деформаций А.А. Ильюшина (жесткое нагружение) при одновременном комбинированном действии на тонкостенный трубчатый образец растяжения-сжатия и кручения. Исследованы скалярные и векторные свойства материала стать 45. Показано, что экспериментальные диаграммы, характеризующие скалярные и векторные свойства материала носят колебательный характер. The paper presents experimental results of deformation of a thin-walled tubular specimen along a smooth curvilinear strain trajectory of constant curvature, in which the sign of curvature changes at each section and its center shifts. Experimental data were obtained on the automated calculation-experimental complex SN-Computer in the deviator space of deformations A.A. Ilyushin (rigid loading) with a simultaneous combined action on the specimen of tensioncompression and torsion. Scalar and vector material properties of steel 45 are investigated. It is shown that experimental diagrams characterizing scalar and vector properties of the material have oscillatory character.

Rigid Loading

For a discrete, or discretized, conservative gradient system, such as is envisaged in catastrophe theory and arises throughout the physical sciences, it is often necessary to assess the stable regions of an equilibrium path that exhibits a succession of folds. At each fold the degree of instability changes by one, so that as the system evolves from a region of known stability the first fold must represent a loss of stability. At a second fold, however, it is not clear whether the system is suffering a further loss, as we shall see in some examples, or is regaining its original stability as is more common in elasticity. A new theorem involving a conjugate parameter allows all such stability changes to be readily assessed on the basis of the form of the equilibrium paths themselves. The application of the general theory to the external and internal stabilities of an elastic structure under dead and rigid loading is demonstrated. Under the former, the load is the control parameter and the corresponding deflection plays the role of the conjugate parameter, while in a direct analysis of rigid loading these roles are reversed. A supplementary study of rigid loading which uses Lagrange multipliers supplies further theorems relating the dual concepts of external and internal stability. The use of the theorems is demonstrated in the buckling of elastic arches and shallow domes, and in the incipient gravitational collapse of a massive cold star. The possible stabilization of bifurcations by rigid loading is examined, and shows how the results can also be of value in bifurcational instabilities.

With increasing attention to global warming, expectations for Floating Production Storage and Offloading (FPSO) System to develop a gas field of which reserve is smaller, or Floating Storage and Regasification Unit (FSRU) as LNG terminal are growing. Offloading transfer of LNG requires rigid loading arm instead of flexible hose because of low temperature of LNG. It involves the relative motion estimation between LNG FPSO/FSRU and a shuttle tanker to design loading arm and to estimate operability of offloading work. The operability in environmental conditions of the sites affects on the decision of the storage capacity and the necessary number of LNG carriers for transportation. For this task of motion study, the motion estimation programs for alongside and tandem alignment have been developed. This paper presents outline of the programs and some validation results. An example of application of the calculation results to design FSRU is also shown.
