Maximum circumferential stress criterion of brittle fracture for v - notch
型切口脆性斷裂的最大周向應力準則 -
Based on the theory of fracture mechanics, the relation between the critical stress intensity factors for v - notch kc and the plane strain crack toughness k10c and the brittle fracture criterion of the maximum circumferential stress for single and double stress singularity with the v - notch problems are proposed. experiments were carried out using two kinds of v - notched specimens made out of plexiglas to verify this brittle fracture criterion
本文基於斷裂力學原理，推導出了型切口的臨界應力強度因子k _ c與材料的平面應變斷裂韌度k _ （ 10c ）之間的關系，給出了平面單奇異性和雙奇異性型切口問題的最大周向應力脆性斷裂準則，並用有機玻璃板材加工了兩種型切口試樣，進行了實驗驗證。
