Purpose-the choice of model, algorithm development and programming to calculate the stress-strain state and stress concentration in composite membranes with holes. The selected model of shells, which used the hypothesis of Timoshenko. Methods-we used the finite element method, wirestone isoparametric quadratic elements with eight nodes. The problem is reduced to the system of linear algebraic equations, the matrix of which is symmetric. The program allows to calculate the concentration factors near the hole. These results can be used in the calculation of apparatuses of the food industry.
