Geotextile, also known as geotextile, is a water permeable geosynthetic material made of synthetic fibers by needling or weaving. The geotextile has the characteristics of high strength, corrosion resistance and good water permeability. The method is widely applied to civil engineering such as water conservancy, electric power, mines, roads, railways and the like.
The geotextile is under the action of tension, bursting force and tearing force in engineering, wherein the tension and bursting force are large, and the tension and the bursting force can be accurately measured by an MTS810 testing machine. Whereas the tear force is small, typically around 300N, which is not within the effective range of MTS810 testers (greater than 1000N). If a force sensor is used in cooperation with an MTS810 testing machine, the tested tearing force is converted into an electric signal through a strain gauge, the electric signal is converted into a digital signal through a strain gauge, strain data obtained through instant testing are input into a computer, and the data are processed through the computer, so that the tearing force of the geotextile is obtained, and the important application value is achieved.
