ABSTRACT = {The purpose of this research is to determine fracture effects of vulcanize elastomer at various thickness to width ratios under opening mode fracture mechanics. The <i>J</i>-integral values from finite element method are compared with those from experiment. In this research, fracture tests perform under Single Edge Notch Tensile (S.E.N.T) tests using the multiple-specimen method. Compare to the experimental data, the numerical results are acceptable at the deep crack length, <i>i.e</i>. high crack length to width ratio. The <i>k</i> values from the 3-D numerical calculation show that thin sheet is dominated by plane stress state, but thick sheet is dominated by plane strain condition. The results reveal that, in 2-D approximation, the plane strain assumption can be used at the thickness to width ratio (<i>t/w</i>) at 0.88 up.},
