On The Critical Void Growth Ratio For Steel CF
CF钢临界空穴扩张比参数的测试研究

Experimental procedure for determining new ductile frature parameter-critical void growth ratio V_ of macroform and R_c/R_o of microform -is introduced.Results for steel CF are presented.The relationship between V_ and R_c/R_o as well as the physical mean- ing of the criterion of critical void growth ratio are described.
