The task of the work is to study the stress-strain state of tubular workpieces in the processes of cutting with the use of modern CAD/CAE systems based on the solution of contact problems of nonlinear analysis. The main prerequisites for solving the problem are considered by numerical methods. The issues of selection of parameters of model materials, description of boundary conditions, construction of finite-element mesh are considered. The composition of the program parameters to be varied during the nonlinear finite-element analysis is determined, practical recommendations are given for adjusting the model to obtain convergence of the solution of the problem of modeling the hole deformation process. When analyzing the quality of the simulation results, the results of experimental studies of such parameters of the deformation process as the deformation force, the size of the hole after the passage of the tool, the distribution of circumferential residual stresses along the thickness of the wall of the part, the length of contact of the mandrel with the workpiece are used. Methods of quantitative determination of the listed parameters according to simulation data have been developed. Prospects for conducting research on modeling processes have been identified.
