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. ***

9522829人这个项目的目的是发展理论的分离“纹理诱导”从“应力诱导”各向异性。 结果将在采用超声波测量和双折射方法的实验中实施。 将考虑两种情况：（a）微晶的初始变形是弹性的，和（B）那些变形是弹塑性的。 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，一个平行于曼和陆的声弹性理论将发展为粘弹性材料。 ***
