摘要
从裂纹技术的需要出发 ,根据工程控制理论和断裂力学的基本原理 ,对控制规则断裂过程做了初步的理论分析 .建立了数学模型和基本分析模型 ,讨论了规则断裂过程的稳定性 。
According to the needs presented by crack technique, a preliminary theoretical analysis of the process of controllable regular fracture is conducted by using the principles of engineering control theory and fracture mechanics, including set up of mathematical model and fundamental analytic model, analysis of the stability of regular fracture process, and set up of stability criterion of crack propagation by means of energy method.
