It is sh-own that the yield stress along one direction and another is synchronized withR-value. Based on the theory of plasticity a formula of σ_(1s)/σ_(7s)=[1+1/R_2)/(1+1/R_1)]~(1/2)was proposed. In statistic estimation, the calculated results after the formula are inbetter agreement with the experimental data. The availability of this formula wasbriefly discussed also. Key words:  Ti plate      yield stress      R-value      Received:  18 June 1989      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1989/V25/I6/131 1 周维贤.TC1钛板的机械性能及其异性情况,西北工业大学科技资料,总字第1059期,1979 2 翟平.TA2M钛板机械性能及各向异性,西北工业大学科技资料,ZHZ8018,1981 3 周维贤.剖面收缩率在评估钛板成形性方面的意义,中国航空学会飞机制造技术学术交流会资料,1988 4 Hill R.
