| Abstract: |
| The strain energy of vulcanized rubber（stored internal energy converted from the stretching or
compression of vulcanized rubber） was calculated by trapezoid grid method and curve fitting method using
tensile test data and EXCEL software. The results of the two methods were accurate and reliable. The higher
the collected raw data density was，the more accurate the calculation results of the strain energy would be. |
