光弹性法测定多裂纹应力强度因子研究

Study on Measurement of Multi-crack Stress Intensity Factors in Photoelastic Method

简要介绍了测定裂纹应力强度因子光弹性法的有关原理,并通过对单、双侧多裂纹应力强度因子测试的试验及试验结果的比较分析,确定多裂纹情况的强度因子,为复杂多裂纹结构的安全评定提供必要的依据。

This paper briefly introduces the relevant operation principle of measurement of multi -crack stress intensity factors in photoelastic method, determines the stress intensity factors under multi- crack conditions through the test for measurement of multi- crack stress intensity factors on single and both sides and comparison and analysis of the test resuits so as to provide the necessary basis for the safety assessment of complicated multi - crack structure.
