Welding of living tissues replaces stitching of tissues with threads during surgical operations. It simplifies and shortens the time of operation performance, lowers their cost and probability of postoperative complications. Water makes up more than half of the biological tissues mass. During welding the melting stage is not clearly expressed. In the post-operative period the weld should be gradually replaced by a healthy tissue without loss of strength. Computer modeling greatly accelerates, simplifies and lowers the cost of studying the mechanical, electromagnetic and thermal processes, running in live tissue welding. Different mathematical packages allow modeling these processes simultaneously. The paper gives an example of mathematical modeling using the finite element method. Its application enables overcoming the difficulties, when studying the processes running in live tissue welding and allows using a 3D computer model, which models the processes of tissues compression and alternating current passage.

The dictionary of physical concepts (terms), which can become, as experience shows, an important component of the educational process, is substantiated and proposed as one of the forms of independent work of students of physical specialties of higher education institutions. Maintaining such a dictionary can be useful for students studying any discipline with some reservations in the guidelines for maintaining a dictionary. [ABSTRACT FROM AUTHOR]

A modified mathematical method of lattice Boltzmann equations is offered. The offered method may be used for numerical modeling of fluid motion, based on finite space structure elements in the neighbourhood of a curvilinear boundary. An algorithm of calculation of probabilities distribution function and of the resultant force acting on the boundary is considered on an example of a two-dimentional problem solving.

It was shown that designing heat-mass exchange processes and devices requires the methods of non-destructive measurement of the real surface area of such an exchange. Since this surface is, usually, very complicated, convolutions of images, obtained in the computer tomograph were proposed. Tomograms of synthetic granite, confirming the technical feasibility of such analysis method and its informativeness in terms of further heterogeneous structure investigation were obtained. Three types of convolutions: convolution in the form of Hausdorff dimensions of the section boundaries, convolution using contraction mapping and convolution using parabolic transformation were considered. The presence of a maximum on the dependence of the heat-mass exchange rate on the working surface convolution results, which allows to formulate and solve the problems of optimizing the parameters of technological processes and designs of heat-mass exchange devices was theoretically justified and experimentally confirmed. Practical testing of the proposed optimization method in designing the packed absorber was performed. As a result of using the proposed method, an increase in the absorber performance by 16-23% without increasing its size was achieved. [ABSTRACT FROM AUTHOR]

The paper deals with studying the possibility of solving contact problems of the elasticity theory, in particular the punch problem using a discrete model of a continuous medium. Mixed boundary value problem of statics of elastic body is solved. Namely, the elastic equilibrium of the body is found if the displacements of some part of its surface points are given. Physically, this corresponds to the case when, using the forces, applied to the surface points, the given displacements are imparted to these points, and the surface is fixed in this form. The difference of the solved contact problems of the elasticity theory is that forces are given for some surface points, and displacements - for others. This work is based on the idea of modeling a continuous medium using the finite-size element. The rectangle, in the corners of which there are point masses, connected by elastic links was proposed as a structural element of the discrete model, replacing the rectangular element of continuous elastic medium. To make calculations for this model it is proposed to use the method of successive displacements, which gave a good account of itself in calculating beam structures. The obtained discrete models allow effectively solve contact problems of the elasticity theory, including at any values of the Poisson's ratio. [ABSTRACT FROM AUTHOR]

Mathematical models of tension and compression processes for one-dimensional solid systems based on behavior analysis at an applied constant load of chains of particles with finite mass are considered. One-, two-, and N-particle discrete models are built. For the latter, limiting transitions to the continuum (continuous models) are performed. The phenomenon of failure of the Hooke's law for all models without considering the mechanical energy dissipation and its validity when taking into account the dissipation is revealed. Relevance of the conducted researches is caused by previously unnoticed paradox: the Hooke's law, which describes the steady state of a macroscopic body with constant load applied to it, is used as the basis for the elasticity theory, equations of which are dynamic. In addition, in the Hooke's law there are no mechanical energy dissipation "traces", which is a very rough idealization. Telegraph tension-compression equation, alternative to the Lame's equation in the elasticity theory is obtained. Unlike the latter, the equation found describes the evolving displacement field and can serve as a basis for generalizations: plasticity and creep equations in homogeneous and heterogeneous media. Relation, corresponding to the Hooke's law and describing the steady state of a deformable rod taking into account the mechanical energy dissipation is obtained. The obtained results are of theoretical and practical importance since determining relations between the Hooke's law and discrete models and deriving telegraph viscoelasticity equations are prerequisites for improving the theory of deformation of solids and for the mathematical modeling of movements of real continuous media (rocks in particular).
