摘要 本文分析了用边界元方法计算固体中超声的散射,提出了一种时间域超声散射计算方法,这种方法能动态显示超声散射的全过程,并和动态光弹照片进行了对比。 Abstract: A time-domain boundary element method has been used to compute ultrasonic pulse scattering field in a solid. The scatterer can be void or solid with different parameter and the boundary ofthe scatterer can be complicate. The computer time can be greatly reduced when scattered sound fields are computed for various incident waves. The results are compared with the pictures of photoelastics.
