SOLUTION OF ENGINEERING TASKS WITH HELP VARIOUS SOFTWARE PACKAGES
The paper considers a mathematical model of the problem of finding normal stresses and strains in the example of the core system. The compiled model is represented by a system of nonlinear equations and inequalities. The problem is solved with the help of various application packages. In the environment of the MS EXCEL tabular processor, the solution was found by the method of a generalized decreasing gradient using the “Solver” tool. The result is confirmed by a decision in the MathCAD software package environment using the Given-Find computing unit. Also, for the problem of soil mechanics, the characteristics studied showed a complete agreement of the calculated data found by various programs.
