| Abstract: | By applying the nonlinear finite element techniques,the rubber materials are respectively analyzed using such constitutive models as Neo-Hookean and Mooney methods.In this respect,a numerical analysis is conducted on corner-inclusive shearing fractures for rubber vibration-reduction spacers.Subsequently,the correlation between shearing stiffness and tearing energy regarding fracture dimension is speculated and compared based on bespoke methods.Furthermore,the bevel-angular fracture depths are analyzed for v... |
