At the mesoscale , the three-dimensional discrete dislocation dynamics ( 3DDD ) is constructed and used to model the dislocation sweep the helium clusters . The constitutive equation for describing the thermally-activated stress of helium cluster is fitted .
在细观尺度上,建立了三维离散位错动力学(3DDD)模型,并模拟了位错克服氦团簇的热激活滑移过程。
