The main objective of this paper is studying the influence of temperature on the elongation of the Chlorinated poly (vinyl chloride) (CPVC), a thermoplastic polymer subjected to thermomechanical tests. The results of tensile tests at different temperature showing the effect of this both environmental and utilization condition on the mechanical behavior of the amorphous polymers. In this context, several many models of the damage quantification of steel material were developed; Miner in 1945 showed a study that the damage evolution is for always linear and proportional to the ratio between the damaged specimen number of cycle and the ultimate number of cycles directly. However non-linear damages models were developed by Shaneley, Valuri, Gatts and Henry showing a different behavior of the materials and an expression of non-linearly damage evolution as a function of the fraction of life. Moreover, in 1971, based on the precedent theories Bui-Quoc established a unified theory. We determined the three stage evolution of CPVC specimens’ damage, in order to plan predictive maintenance consecutively to intervene at the optimum time and ensure the reliability of our structures. This paper also includes a numerical validation part for the measurement of the global characteristics of the studied material during temperature change; compared with the experimental results.
