摘要
本文概要介绍了新的韧断特性参数,即临界空穴扩张比的宏观形式 V_(GC)和细观形式 R_c/R_o 的测试方法及对 CF 钢制试件的实测结果.论述了宏观参数 V_(GC)与细观参数 R_c/R_o 二者的关系.阐明了临界空穴扩张比判据的物理意义.
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.
