Objectives of studying the discipline |
The aim of the course is to study the models, methods and methods for solving the problems of all the sections of continuum mechanics.
– use the basic equations of continuum mechanics in the formulation of specific educational and applied problems; – apply knowledge in the field of differential and integral equations, the theory of functions of a complex variable in the solution of these problems; – apply approximate, asymptotic and numerical methods for solving the problems of mechanics of a deformable solid |
