critical stress fracture toughness 中文意思是什麼
critical stress fracture toughness
解釋
臨界應力斷裂韌度-
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。 -
With this in minds, many researchers have proposed a variety of models for describing the nonlinear fracture of concrete for the past decades. amid them most take the critical stress intensity factor kic as the fracture toughness, a sign of ability to resist the crack extension
對此,在過去的幾十年裡,眾多研究人員提出了很多描述混凝土非線性斷裂的模型,而其中的大多數斷裂模型都以臨界應力強度因子k _ ( ic )作為抵抗裂縫擴展阻力的斷裂韌度。
