3 Terms and Definitions
This document does not contain any terms or definitions that need to be defined.
4.Experimental Principle
Axial pressure is applied by the axial loading device of the triaxial stress testing machine, and confining pressure is applied by the confining pressure loading device. The measurement system realizes the parameter measurement.
The measurement and control, data acquisition and processing system realizes the acquisition of mechanical data and the processing of stress-strain curves under test conditions, according to the...
The elastic modulus of the oil well cement slurry is obtained by calculating the relationship between force and strain.
