ABSTRACT
Finite element method is very widely used in practice for numerical estimation of stress-strain states and mechanical behavior of soil, homogeneous and heterogeneous media, composite materials and constructions and so on. A distinctive feature of the UniWay programming complex is its object-oriented nature. The main principles of the object-oriented approach are not new, however, only in the object-oriented approach they have been implemented for the decision of a general problem. All the algorithms, functions and methods of the program were developed in accordance with the laws of mathematical abstractions. Also the hierarchy of the classes and the laws of interaction of the objects of these classes were developed. In the software there is realized an isoparametric model of finite elements 1D, 2D and 3D for a continuous medium. The software includes the models isotropic and ortotropic elastic materials, nonlinear elastic materials, models of deformation type and elastoplastic yielding, visco-elastoplastic model of Binhgam’s type. Above-mentioned programming complex was used for analysis the composite materials stress-strain state, for an investigation of stress-strain state and stability of the underground complexes, for the hydropower dams and slopes. It was also used for estimation of effective parameters of mechanical properties of polymer composite materials and rock masses.
