本文证明了三点弯曲试样的弹性转动因子只是a/W的函数,并给出了表达式。本文还研究了三点弯曲试样裂纹咀无量纲张开位移及H函数与刀口无量纲张开位移及刀口H函数的关系,并分别给出了表达式。
This paper proves that the elastic rotation factor of a three-point bending specimen is a function of a / W and the expression is given. In this paper, we also study the relationship between the non-dimensional open crack of the crack tip and the dimensionless flared opening and knife edge H function of the three-point bending specimen, and give the expression respectively.
