SCATTERING OF ELASTIC WAVES BY MULTIPLE NON-COP-LANAR PENNY-SHAPED CRACKS IN A LAYERED MEDIUM
-
摘要: 本文在[1]的基础上,利用 Hankel 积分变换,进一步研究了层状介质中多个非共面硬币形裂纹的弹性波散射问题。从所得结果来看,虽然层状介质中多个非共面硬币形裂纹的弹性波散射问题在形式上与多个非共面穿透形裂纹问题[1]有惊人的相似之处,但两者之间有着质的差异。Abstract: Based on the reference [1] , using Hankel integral transform, a rigorous theory of the scattering of elastic waves by multiple non-coplanar penny-shaped cracks in a layered medium is presented in this paper. From the obtained results, it is shown that the problem is astonishingly similar in form to the case of Griffith cracks [1] , but there exts inherent differences between the two cases.
