Summary In an ideally plastic material any principal axis of the stress tensor is also a principal axis of the strain rate tensor. It is shown here that in plastic flow also the reverse is true. Besides, the validity of either statement is discussed for materials obeyingPrager's hardening rule or its modification proposed by the author. 相似文献

Becker has shown in [1] that for the 4-th Pythagoras number of the field (X) the inequality P4 ((X)) 36 holds. In this paper we will show P4 ((X)) 24 and P4 (K) 3 for all real pythagorean fields K. 相似文献
