Shape memory alloys are referred to as a group of alloys that can retrieve the permanent deformation and strain applied to them and eventually return to their original form. So far, various studies have been done to determine the behavior of these alloys under cyclic loading. Most of the studies have mainly been conducted by using the foundations of Continuum Mechanics in order to examine the properties of memory alloys. In this study, instead of using the Continuum Mechanics, a Molecular Dynamics simulation method using Lennard-Jones potential is utilized. The changes in the behavior and properties of memory alloy under cyclic loading are being examined. First, the functional form parameters for the Lennard-Jones potential are solved. Subsequently, these parameters are implemented to evaluate the response to thermal cyclic loading. The results of this study provide a better understanding of the behavior of memory alloys under cyclic loading.

形状记忆合金循环马氏体相变下的显微组织生长研究 分子动力学方法

形状记忆合金被称为一组合金,它们可以恢复施加于它们的永久变形和应变并最终恢复到它们的原始形式。到目前为止,已经进行了各种研究来确定这些合金在循环载荷下的行为。大多数研究主要是通过使用连续介质力学的基础进行的,以检查记忆合金的性能。在这项研究中,不是使用连续介质力学,而是使用了使用 Lennard-Jones 势的分子动力学模拟方法。正在研究循环加载下记忆合金的行为和性能的变化。首先,求解 Lennard-Jones 势的函数形式参数。随后,实施这些参数以评估对热循环载荷的响应。
