| 摘 要： | 在弹性波理论中,对弹性波导如板、壳、柱等的研究,一直受到人们的重视.随着断裂力学的发展和应用,含裂纹的弹性波导问题引起了人们的关注.在工程实际中,人们希望得到更多的关于带裂纹的管路中弹性波传播时的某些特性,尤其是远场信息,因为它将直接为探伤技术等应用领域提供理论依据.在前文中我们讨论了其应力场在裂纹尖端附近的力学行为,在此我们将着重分析其位移场在离开裂纹时的远场特性.

| Abstract: | In this paper, an analysis of the interaction of steady longitudinal waves with an annular part through a oraok located in an infinitely long hollow cylinder has been investigated. Using the integral transform technique, the problem is reduced to a second kind of Fredholm integral equation, which is then solved numerically. And finally, the feature of displacements at the far-field has been discussed in detail. |
