摘要
从系统的角度出发,运用耗散结构理论,对岩石类材料的极限承载力、破裂过程及其变形过程中的能量变化、宏观应力-应变关系等进行深入的分析,从而更深入地揭示岩石类材料力学特性的本质。研究结果表明岩石类材料变形系统具有耗散结构的特性,岩石受力产生变形是非线性动力学过程,即系统内部各要素之间发生协调和相干效应,岩石承载力(强度)是外界做功功率和岩石自身耗散能率达到平衡的外在力学表现。
The deformed system of rock generic material has characteristics as dissipation structure. The ultimate carrying capacity, fracture process and stress-strain relationship on rock generic material are studied with dissipation structure theory in this paper, which shows the essence of mechanical characteristics on rock generic material can be studied deeply from the point of view of system and energy.
