Приближенное решение обыкновенных дифференциальных уравнений второго порядка
(БНТУ, 2004)The new method ofproblem solving of Cauchyfor differenńal second-kind equations with variable coefficients is offered which rests on a reduction of this equation to the equation Rickati. The solution last is under construction on the basis of a method of a linearization. The estimates of approximation of the precise and approximate solution are given.2020-06-15 -
Применение информационных компьютерных технологий в учебном процессе
(БНТУ, 2004)Some problems of construction of the automatized training system (ATS) of applied mechanics are touched in this article. The ATS consists of two information blocks: an electronic directory and control-checking system. The electronic directory includes some amount of numbei-ed contexts. Questions of a different level of difficulty form this testing system. Question's selection is ...2020-06-15 -

Применение объектно-ориентированных языков программирования в задачах МДТТ
(БНТУ, 2004)Today the object-oriented program language became more and more applicable. To solve problems by the method of finite element is the most appropriate way to know a lot about these lang. And, on the other hand, the object-oriented languages of programming can make quite lacier the method of finite element realization. In the following we consider the whole cycle the method of ...2020-06-15 -
Применение программного комплекса ANSYS для иллюстрации некоторых положений механики
(БНТУ, 2004)There are considered variants ofapplication of ANSYS program product at holding occupations for the students studying courses of mechanics under the abbrex’iated course. The opportunities of the program promoting an enhance of student s knowledge are shown by the example ofproblem solving about a bending of a beam with opened profile, shell stability, a deformation of a reinforced ...2020-06-15 -
Разрешающая способность метода осреднения и статистического обращения для идентификации макро- и микроструктуры среды
(БНТУ, 2004)Let us consider the problem of resolution of the method of averages and statistical inversion methodfor the identification of macro- and microstructure of a medium. The quality of identification is essentially affected by the distribution of the sources of detecting emission and the receivers of dispersed field. These problems are wide investigated in many papers. We will restrict ...2020-06-15 -
Расчет кинематических параметров в сферических координатах матричным методом

Расчет тонкостенной конструкции, состоящей из элементов гофрированных панелей
(БНТУ, 2004)The thin-walled structure lied in a soil is investigated. The reaction of the structure on the part of the external elastic filling (a soil) is considered in the scope of Gook’s law. General solutions of the governing equations describing the structure equilibrium are obtained. The substitution of the general solutions into the boundary and conduction conditions leads to the ...2020-06-15 -
Свойства поверхностных акустических волн в монокристаллах кубической сингонии
