| In recent years, there has been a large increase in the use of polymers in engineering applications. Along with this increase use will almost assuredly come failures. Chlorinated-PVC (CPVC) is a material designed to withstand higher temperature than PVC. For this reason, understanding the mechanical properties under different loading rates and temperatures has become increasingly important.; In this thesis work, strain rate (crosshead speed) and temperature dependence of fracture toughness and tensile properties of CPVC pipe material is investigated. Single-Edge-Notch Bending (SENB) and tensile specimens are used for fracture toughness and tensile tests, respectively. Five temperatures (-10, 0, 23, 50 and 70°C) and three crosshead speeds (5, 50 and 500 mm/min) are considered in this study.; The results showed that both ductile and brittle fracture modes are possible. At 50°C, brittle to ductile transition behavior is observed. (Abstract shortened by UMI.)... |
