This paper proposes and studies three methods for the identification of cracks in linear elastic bodies. They are based on the reciprocity gap principle which they extend to the case of partially redundant boundary data. The methods are all assessed on an academic 2D case, then the most appealing is more deeply analysed and illustrated on a 3D test-case.

往复间隙法在线性弹性边界数据不完全的情况下识别裂纹

本文提出并研究了三种识别线性弹性体中裂纹的方法。它们基于互惠差距原则，并适用于部分冗余边界数据的情况。这些方法都是在2D学术案例中进行评估的，然后在3D测试案例中对最吸引人的内容进行更深入的分析和说明。
