Документ О влиянии кинематических гипотез на характер контактного взаимодействия цилиндрической оболочки с бандажом(НТУ "ХПИ", 2006) Львов, Геннадий Иванович; Ткачук, А. Н.The article is devoted to research of contact interaction between thin cylindrical shell and rigid bandage. All possible types of contact interaction and lengths of contact zones are obtained for different shell parameters and shell formulations. The obtained results are given by means of diagrams on parameter planeДокумент Исследование влияния механических характеристик материала на характер деформирования рабочих колес центробежных компрессоров(НТУ "ХПИ", 2006) Бухолдин, Ю. С.; Левашов, В. А.; Львов, Геннадий Иванович; Костромицкая, Ольга АнатольевнаThe influence of a yield stress value on character of elastoplastic deformation and elastic unloading of the working wheel under inertial loading is investigated. The realization of the large number of calculation variants by a of finite-element method shows, that there is a so-called critical value of a yield stress. It is not recommended to use materials having a yield stress lower of this critical value, for making of working wheels of centrifugal compressors, as it will result in redistribution of a deforming picture, appearance of the large bending moments and displacements, which after unloading do not disappear
