THE COMPUTATION OF TEARING ENERGY OF NICKED RUBBER STRIPS IN EXTENSION

To compute the tearing energy of nicked rubber strips in extension, one has to solve first the associated stress-deformation involving finite elasticity. In the past, this was a formidable task so the tearing energy was determined solely by experiments and only for a few test pieces. With the aid of the finite element method (FEM), it is shown that this may now be done simply through the use of the Rice's J integral. Tearing energy for two test pieces are computed and results compared with existing experimental data. The agreement is good.
