Abstract
This article presents a theoretical analysis of the calculation of the stress-strain state of a joint two-layer drawing with thinning workpiece, taking into account the friction forces by using the power balance. The analysis of key parameters of the stress-strain state of the process of drawing with thinning. The proposed model for calculating the process of drawing with thinning two-layer workpiece, which takes into account the main factors that affect the process of deformation, such as the geometric parameters of the layers of material and equipment, the mechanical properties of the metal layers of the workpiece, the friction force of contact, and others. It is shown that the error in the calculation results for perfectly plastic material without the friction forces and the calculation taking into account the friction forces for the process of drawing with thinning does not exceed 10-11 %, accuracy of numerical calculation does not exceed 5-6 %.
