Summary: The method of determination of stresses in cylindrical shell with two holes on one guide was given. The shells model of Timoshenko was used. The method of finite elements was used. The strain distribution around the holes on changed of shear stiffness of shell material was investigated.

Key words: stress, shell with circular opening, finite elements method.

Summary: In this article, the application of the MathCAD software package for solving differential equations with partial derivatives is considered.

Key words: mathematics editor, differential equations, partial derivatives.

Summary: This article discusses the use of MathCAD software to solve differential equations of the first order.

Key words: mathematics еeditor, differential equations, Lagrange method.

Summary: we consider the different types of software that allow to make calculations for engineering and mathematical problems.  Their strengths and weaknesses  explored.

Key words: mathematics editor, finite elements method, engineering modeling.

Summary: The solution of the problem of stresses distribution in shells made of composite material with opening is given. The finite elements method was used. The influence of transversal shear on the stress concentration in the cylindrical transversely isotropic shell with circular opening was investigated.

Key words: stress, shell with circular opening, finite elements method.
