Abstract

Unplasticized PVC pipes were tested using static and dynamic testing conditions. The static test was performed by pressurizing the pipes at a strain rate of 1 × 10⁻⁴ s⁻¹ and the dynamic test was carried out using a drop hammer apparatus at a strain rate of 8 s⁻¹. The most pronounced influence of the high strain rate was a reduction in the failure hoop strain and an increase in the Young's modulus. An empirical formula was fitted to the stress-strain curves to represent the nonlinear and strain rate dependent behaviors.
