| Abstract |
Earlier, the authors developed a method for reducing boundary value problems in continuum mechanics for systems of differential equations to boundary value problems for individual equations, called scalar. This approach is based on the B. G. Galerkin transformation for systems of partial differential equations and the block element method. In this article, based on the well-known properties of the block element method, three approaches are developed that make it possible to implement the application of the block element method to fairly complex scalar boundary value problems. For the first time, by analogy with the exponential substitution used in ordinary differential equations with constant coefficients, a block substitution is used in this article, which makes it possible to solve boundary value problems for partial differential equations. As a result of the study, the sought solutions of scalar boundary value problems are represented as a sum using the simplest block elements, which greatly simplifies the study of the exact solutions obtained. |
