Explanation of commonly used parameters in rubber tensile test

Rubber is a kind of latex in plants. After processing, it becomes an elastic and impermeable material. Sometimes necessary tensile tests are performed on rubber. The following is a specific understanding of common parameters in rubber tensile tests.

1. The force value (tensile strength) that occurs during the sample stretching to fracture;

2. Force value (breaking strength) when the sample is broken;

3. The force value corresponding to the yield point (tensile stress at the yield point);

4. The force value (fixed extension stress) when the sample is stretched to a given elongation;

5. The elongation rate of the sample when stretched to a given stress (fixed stress elongation);

6. Elongation corresponding to the yield point (elongation of the yield point);

7. Elongation rate when the sample is broken (elongation rate when it is broken).
