摘要
叙述了如何运用有限元方法对KⅠ型裂纹断裂韧度测试试验进行数值模拟,并阐述了运用位移法估算裂纹强度因子的过程和方法,重在阐明使用有限元数值模拟计算岩石Ⅰ型裂纹应力强度因子的准确性和可行性。
This paper introduces the test which uses finite-element method to simulate K Ⅰ -type crack fracture toughness, and also presents the procedure and method which applies displacement method to estimate crack intensity factor. It emphasizes on illustrating its accuracy and feasibility which can use finite-element numerical simulation to compute rock Ⅰ -type crack stress intensity factor.
