Test principle
The sample is clamped between the two collets of the fixture, and the two collets move relative to each other. Through the force sensor located on the dynamic collet head and the displacement sensor built in the machine, the change of force value and displacement in the test process are collected, so as to calculate the tensile, tearing, deformation rate and other performance indicators of the sample.
