In the field of materials science and engineering, environmental stress cracking testing machines are important testing equipment used to evaluate the durability of materials under specific environmental conditions.
Application
The stress cracking strength of polyolefin geomembrane was measured and evaluated by notch constant load tensile test. During the test, the dumbbell sample with notch prepared in advance is placed in the thermostatic surfactant under constant load tension, and the fracture time of the sample is measured and recorded. A series of test results under different stress levels can establish a relationship between the stress level and the fracture time on the logarithmic axis.
