16-Year Creep of Polyethylene and PVC,
Abstract
Creep tests at constant stress, temperature and relative humidity for two thermoplastics were conducted for approximately 132 000 hr. The strains for the first 2000 hrs were described by an equation. This equation was found to predict the creep of PVC for approx-imately 132 000 hr. with reasonable accuracy. The predicted strains for polyethylene were somewhat low. Strains during unloading and reloading after 90 000 hr. of creep were pre-dicted reasonably well by the Boltzmann superposition principle. (Author, modified-PL)
