Abstract

The article reports the experimental data on brittle rock strength from the bending tests of beams and from diametrical fracture of disk specimens with an axial hole. The author uses the nonlocal fracture approach and compares the strength from the tests with the tensile strength of rocks. It is shown that the different geometry fracture tests allow determining the structural parameter of a medium.

非均匀应力场中结构性岩石和材料的断裂

摘要

本文通过梁的弯曲试验和具有轴向孔的圆盘试样的径向断裂，报告了脆性岩石强度的实验数据。作者使用了非局部断裂方法，并将测试的强度与岩石的抗张强度进行了比较。结果表明，不同的几何断裂试验可以确定介质的结构参数。
