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.

形状记忆合金试样孔的冷塑性变形建模

形状记忆合金板孔的冷塑性变形过程是通过设置机械特性和正反相变开始和终止温度的有限元方法模拟的。通过使用 ANSYS Workbench 软件，我们可以确定功能孔附近板中残余应力的分布。最高的法向压应力和拉应力分别形成在板的中部和距孔边缘 2-4 mm 处。
