| 摘 要： | 根据焦散线的形成原理，以及含I型裂纹试件受力前后光程差与
声程差表达式的相似性，提出了声焦散线的概念，得到了声焦散线沿
横向最大尺寸与应力强度因子的关系，为通过声焦散线法确定应力强
度因子打下了基础.

| Abstract: | Based on caustic formation principle and on similarity of the expression of optic path differ- ence to that of acoustic path difference for mode I cracked specimen, the concept of acousto-caustics is introduced, the relationship between the maximum transverse dimenision of acousto-caustics and stress intensity factor is obtained and the basis for deter- mining stress intensity factor by acousto-caustics is provided. |

| Keywords: | acousto-caustics optic path difference acoustic path difference stress intensity factor |
