Studies in Acoustoeleasticity, Acoustoplasticity, and Acoustoviscoeleasticity

[9522829] Man该项目的目的是发展“织构诱导”和“应力诱导”各向异性的分离理论。结果将在采用超声测量和双折射法的实验中实现。将考虑两种情况：(a)晶体的初始变形是弹性的，(b)这些变形是弹塑性的。利用定量织构分析的语言和方法，明确了织构对双折射的影响。此外，粘弹性材料将发展与Man和Lu的声弹性理论平行的理论。＊＊＊

9522829 Man The objective of this project is to develop theories for the separation of "texture induced" from "stress induced" anisotropy. The results will be implemented in experiments that employ ultrasonic measurements and the birefringence method. Two cases will be considered: (a) the initial deformations of the crystallites are elastic, and (b) those deformations are elastic- plastic. By using the language and methods of quantitative texture analysis, the effect of texture on birefringence will be made explicit. In addition, a parallel to the acoustoelastic theory of Man and Lu will be developed for viscoelastic materials. ***
