Abstract
The process of cold plastic deformation of a hole in a plate made of shape-memory alloy is simulated by the finite-element method by setting the mechanical characteristics and the temperatures of the onset and termination of direct and reverse phase transformations. By using the ANSYS Workbench software, we determine the distribution of residual stresses in the plate in the vicinity of a functional hole. The highest normal compressive and tensile stresses are formed in the middle part of the plate and at a distance of 2–4 mm from the edge of the hole, respectively.
