On the basis of the proposed model, we study the phase and stressed states of titanium-nickelide plates under the conditions of bending and heating-and-cooling by using the methods of continuum mechanics and thermodynamics of nonequilibrium processes with an aim to get a quantitative description of the behavior of bodies made of shape memory materials. We perform calculations for various combinations of mechanical loads and temperatures. It is shown that, under the conditions of phase transformations in the plate, we observe the appearance of a distribution of martensite with variable thickness, which leads to the formation of an inhomogeneous residual stress-strain state.

钛镍合金板在热机械载荷下的应力状态和相状态建模

在该模型的基础上，利用连续介质力学和非平衡过程的热力学方法，研究了钛镍合金板在弯曲和加热冷却条件下的相态和应力状态，以得到定量分析。描述由形状记忆材料制成的物体的行为。我们对机械载荷和温度的各种组合进行计算。结果表明，在板内相变的条件下，我们观察到厚度可变的马氏体分布的出现，这导致形成不均匀的残余应力应变状态。
