Abstract

In this paper, the energy release energy corresponding to the unit crack propagation obtained from the displacement controlled load-displacement plot is equalized to the elastic energy release rate, and the variation of stiffness based on the crack length is obtained. For this purpose, instead of measuring the amount of crack mouth opening in the single edge-cracked tensile specimen, the extensiometer elongation amount was taken in the middle part of the specimen. Thanks to the equality of the stiffness to the crack length, the transformation of the load-displacement curve into the material resistance curve was realized.
用一般位移求断裂阻力曲线
在本文中,从位移控制的载荷-位移图中获得的对应于单位裂纹扩展的能量释放能量与弹性能量释放率相等,并获得了刚度基于裂纹长度的变化。为此,不是测量单边裂纹拉伸试样中的裂纹开口量,而是在试样的中间部分取伸长计伸长量。由于刚度与裂纹长度相等,实现了荷载-位移曲线向材料阻力曲线的转换。
