The paper considers the problem related to the compensation of springing in the fitting of parts produced by longitudinal stretching. The imitating modeling of shaping by longitudinal stretching using elasto-plastic model of material taking into account anisotropy was carried out on the example of one element. The adequacy of modeling was checked according to the following criteria: deformation ratio; thinning; Keller-Godwin’s chart and required shaping force. Conclusions were drawn on the adequacy of modeling. Implicit calculation of springing gradients in an element was carried out and thus the iterative calculation of compensation of springing in the fitting. The negative effect of springing compensation at such scheme of shaping is shown. Change of the springing size in the course of iterative calculation of springing compensation in the fitting is also shown.
