摘要
简要评述超声检测过程的数值模拟 ,探讨超声波声场的模拟、超声波和缺陷的相互作用、换能器 缺陷检测系统、超声波在材料和构件中的传播路径。
The numerical simulation technique for ultrasonic testing is reviewed. The simulation of ultrasonic field, the interaction between ultrasonic waves and defects, the inspection system including transducer, the path of ultrasonic waves in materials and structures, probe design and the reliability of ultrasonic testing are discussed.
