摘要(Abstract)：

固体内耗是固体材料在振动中所引起的能量损耗，与其阻尼性能密切相关，在微观上是原子弛豫及原子结构演化的反映，能够加深对固体材料缺陷弛豫动力学的理解。分子动力学是研究固体材料的重要方法，可在微观上直观观测结构及动力学演化，具有目前实验不可企及的优势。本文从理论推导固体内耗参数，并应用分子动力学方法给予表征，结合上机实验加深同学们对固体内耗的理解，进一步概述固体内耗研究前沿，这对于固体力学粘弹性教学具有重要启发价值。本文结合固体内耗理论知识及作者多年的内耗研究成果，从教学方法改革、教学内涵及教学过程设计等多方面探讨该课程教学，讲授了固体内耗本质及分子动力学在内耗方向的应用，深化了固体内耗教学效果。

关键词(KeyWords)： 固体内耗;分子动力学方法;教学方法;非晶合金
