Розробка методів розв'язання змішаної теорії пружності для багатозв'язного півпростору Head Shevchenko V.P., Registration Date 24-03-2003 Organization Donetsk National University popup.description2 The numerical-analytical method of definition of a two-dimensional stress state multiconnected anisotropic half-spase, containing concentrators of stresses such as cavities, elastic inclusions and cracks is developed. On the basis of this method distribution of stresses, density of potential energy and change KIN (is investigated in case of cracks) in half-spase at various combinations and arrangements of cracks, inclusions and cavities. The method of two-dimensional integrated transformation Fourier constructs the fundamental decision thermoelastisity ortotropic cylindrical shells. Linear distribution of temperature on thickness of the shell is stipulated. It was taken into account convection heat exchange with an environment which has distribution under the law of Newton. The stress state the transversal-isotropic spherical shell with circular rigid inclusion is investigated depending on the sizes of inclusion. Numerical researches establish a line of practically important mechanical laws of change of an stress state of bodies which need to be taken into account at designing various machines, mechanisms, underground excavation Product Description popup.authors popup.nrat_date 2020-04-02 Close
