Problems solved by technology

However, during the current Brazilian splitting test, stress concentration often occurs at the loading point, and since the structure of the loading output end is fixed, the influence of the loading output end on the test results cannot be measured
In addition, the loading angle cannot be determined, let alone the influence of the loading angle on the test results

Abstract

The invention discloses a variable parameter combination Brazilian splitting stress-strain test device. The device comprises a data acquisition system, and also comprises two loading structures symmetrically arranged on an upper part and a lower part of a Brazilian splitting sample, the loading structure comprises a steel structure outer loop and at least a loading arc block, and the loading arc block is fixed on the steel structure outer loop. The invention also discloses a variable parameter combination Brazilian splitting stress-strain test method. According to the test device and the test method, tensile strength of rock brittle materials with different friction coefficients and different loading angles can be tested, the obtained data is accurate and reliable, combination of different impact factors can be carried out, and operation is simple.

Description

technical field [0001] The invention relates to a Brazilian split stress-strain test device and a test method, in particular to a Brazilian split stress-strain test device and a test method with variable parameter combinations. Background technique [0002] Brazilian splitting is the most commonly used tensile strength test method for measuring brittle materials such as rocks. One of the remarkable characteristics of rock materials is that their tensile strength is much smaller than their compressive strength. Therefore, when a rock in a complex stress state is damaged, it often breaks at the place where it is subject to greater tensile stress. Among the mechanical properties of rock, tensile failure is an important phenomenon worth studying. However, during the current Brazilian splitting test, stress concentration often occurs at the loading point, and since the structure of the loading output end is fixed, the influence of the loading output end on the test results canno...
