Using the method of linear response theory in lattice dynamics on the basis of Tyson's model, the response displacements of atoms on cleavage plane at the incipience of brittle fracture was derived and an expression for evaluating brittle fracture surface energy of metals was found.

本文在Tyson模型的基础上，应用点阵动力学线性响应的理论方法，导出了脆断发生时解理面上原子的响应位移，并进而给出金属脆断表面能的计算公式。这种处理方式既保持了解理断裂面是结晶的表现，避免了局域"熔化"和"沸腾"模拟脆断的简单模型中出现的非晶化问题，也对解理面上原子临界位移做了合理估计，避免了人为规定临界位移的随意性，同时，从理论上得出的脆断时产生的声发射信号与实际探测到的量级相近。

Based on some principal rules of brittle rocks polyaxial tests and previous researches, three controlling failure types for brittle rock are obtained. The first type represents the brittle failure controlled by extension microcrack under the condition of lower hydrostatic pressure; the second represents the ductile failure controlled by friction sliding action under the condition of higher hydrostatic pressure when microcrack is close; and the third represents brittle-ductile failure type controlled by multiple factors mentioned above under the condition of high hydrostatic pressure when some microcracks are open and others are close.

通过分析脆性岩石多轴试验中的强度和破坏规律，在已有研究成果基础上，将其强度和破坏控制类型主要归结为3种：类型1，低静水压力时裂缝张开扩展，主要表现为张性微裂缝控制型脆性破坏；类型2，静水压力很高时，裂缝闭合，主要表现为摩擦滑移控制型延性破坏；类型3，处于两者之间时，微裂缝一部分张开，一部分闭合，主要表现为两者复合控制型脆延破坏。
