摘要：

A filled polybutadiene elastomer, typical of that used in the construction of golf balls, is tested at high (> 5000s(-1)) and low (< 0.50s(-1)) strain rates. By using nonlinear least-squares estimation, limited to a physically realizable search domain, suitable parameters are found for the Bergstrom-Boyce model of time dependent finite strain elasticity. These parameters are shown to successfully represent the material behavior over this broad range of strain rates.
