马氏体相变原子模型中异宿行波的不存在性是本研究的重点。假设弹性能量是分段二次的,两个威尔斯井代表两个稳定阶段。我们证明,有没有行波加入有界应变在不同的威尔斯的这种潜在的一个范围内的波速显着低于声速。我们实现这一点使用的轮廓校正方法以前用于显示存在的行波在较高的亚音速速度相同的模型。
The nonexistence of heteroclinic travelling waves in an atomistic model for martensitic phase transitions is the focus of this study. The elastic energy is assumed to be piecewise quadratic, with two wells representing two stable phases. We demonstrate that there is no travelling wave joining bounded strains in the different wells of this potential for a range of wave speeds significantly lower than the speed of sound. We achieve this using a profile-corrector method previously used to show existence of travelling waves for the same model at higher subsonic velocities.
