  • Pure bending of hereditary viscoelastic rectangular plates

    On the basis of the proposed Timoshenko S. P. solution of the problem of pure bending of an elastic rectangular plate under the action of moments of constant intensity acting on its boundary, the theory of bending of viscoelastic plates fixed in the vertices is proposed for the first time. The proposed solution uses the hereditary theory taking into account the hypothesis of N. H. Harutyunyan about the constancy of the coefficient of transverse deformation. For the first time, a method of recalculation of the distributed transverse load applied on the surface of the plate at equivalent moments of constant intensity, time-dependent and applied at the edges, is proposed. For the first time with the help of this theory, the problem of bending a plate pinched at a single angular point distributed by a transverse load is solved. As examples, calculations of rectangular plates under the action of their own weight are given.

  • Calculation justification of the method of using removable load-lifting devices when moving ellipsoid bottoms of nuclear power plant hull equipment

    A calculation for the strength and stiffness of a removable grip with a geometric closure for moving and turning ellipsoid bottoms of the steam generator is presented. The proposed design solution will improve the safety of operation of nuclear power plant hull equipment and reduce the labor and material consumption of technological equipment by eliminating the welded load-handling and installation elements

    Keywords: removable load-grabbing devices, turning and moving, plot of bending moments, calculation of stiffness, thickness of the grip

  • A systematic approach to the implementation of interactive forms of learning during lectures on technical subjects at university

    The introduction of new standards of higher education, especially the mentality of today's youth lead to the fact that the established methods of teaching classes in high school, by the way, is still widely practiced, do not allow the full interest of students and to provide high efficiency of development of the subject. In connection with the above, great interest is holding lectures with interactive forms obucheniya.Odnoy of the most effective and low-cost training in interactive forms a lecture scheduled errors (lecture-provocation). Teach people to think, quickly analyze professional situations, to act as experts, to work in a team - all this is possible if we use different kinds of interactive activities, including this kind as to the planned lecture errors.

    Keywords: systematic approach, improving the efficiency of the educational process, lecture scheduled errors, interactive activity, activation of learning and cognitive activity, technical discipline

  • The use of modern educational technologies in the study of mechanics

    The paper presents the modern techniques and methods of system approach to the organization of the learning process mechanics. We consider some examples of the use of educational technologies and forms of management of educational process, allowing largely to optimize the educational and cognitive activity of students. Called active methods of training, aimed at studying self-mastery knowledge and skills in the process of active mental and practical activities.Interactive learning is a special form of organization of educational activity, which is a joint activity of students in mastering of educational material, the exchange of information and knowledge.

    Keywords: effectiveness of learning, active and interactive forms of learning, the education system, improving the efficiency of the educational process
