超塑胀形中力学量在平面系的向量表示

Representation with Vectors in Plane Triangular Co ordinates for Mechanical Quantities of Superplastic Bulging

在超塑性变形力学的研究历史中，Ｔ．Ｃ．Ｈｓｕ等人的工作有重要的理论价值，遗憾的是长期以来在超塑性力学理论的研究中并未受到足够的重视。他们工作的要点是揭示了应力偏张量、应变张量和应变速率张量可在平面三角坐标系用３个向量表示，这对于超塑性解析力学的研究工作非常重要。对Ｔ．Ｃ．Ｈｓｕ等人［１～５］的工作进行概括的论述，旨在为超塑胀形定量力学解析理论的深入研究提供必要的理论基础。

The work of T.C.HSU et al have had an important theoretical value during the research history of superplastic deformation mechanics,however,it is very pity that their theory has not been paid enough attention to for so long,and the essence of the work reveals the deviation stress tensor,strain tensor and strain rate tensor to be represented by vectors in plane triangular co ordinates respectively.That is very important to the research on superplastic analytical mechanics.This paper makes a comprehensive outline on their work in order to provide the necessary theoretical base for further research on quantitative analytical mechanics of superplastic bulging.
