摘要
介绍超声无损检测中的导波技术,给出该技术中一些特征的表现形式,如相速度、群速度与频散,并对无损检测中常见的SH模式导波、细棒中的导波以及兰姆波作了简要的分析.
An introduction of guided waves in ultrasonic NDT is given. Some of their characteristics are presented, such as phase and group velocities, dispersion. Several typical guided waves including SH waves in a plate, ultrasonic waves in a rod and Lamb waves are also briefly described.
