Longitudinal tear propagation with strain stiffening: Gent hyperelastic material: a Energy release rate versus Pressure with varying $J_m$ at ${\alpha }_{\text{lim}}$ = ${30}^{\circ }$, $H_2$/R = 0.2, and $H_1$/$H_2$ = 0.5. b Energy release rate versus Pressure with varying thickness ($H_2/R$) at $J_m=1$, ${\alpha }_{\text{lim}}$ = ${30}^{\circ }$ , and $H_1$/$H_2$ = 0.5. c Energy release rate versus Pressure with varying tear depth($H_1/H_2$) at $J_m=1$, ${\alpha }_{\text{lim}}$ = ${30}^{\circ }$ , and $H_2$/R = 0.2. d Energy release rate versus Crack angle (${\alpha }_{\text{lim}}$) with varying pressure at $J_m=1$, $H_2$/R = 0.2, and $H_1$/$H_2$ = 0.5
