Estimation of Burst Pressure of PVC Pipe Using Average Shear Stress Yield Criterion: Experimental and Numerical Studies

Polyvinyl chloride (PVC) pipes have been extensively applied in water supply network fields. Understanding the mechanical properties and burst pressure of PVC is necessary because a large number rupture due to excessive internal pressure. In this paper, practical approach based on average shear stress yield (ASSY) criterion was proposed assess pipe addition, uniaxial tensile tests were carried out determine material characteristic parameters pipe. Furthermore, finite element analysis (FEA) also performed tangent intersection (TI) method validate experimental results. Moreover, impact size, such as strain hardening exponent standard dimension ratio (SDR) bursting pressure, investigated. The comparison with theoretical model FEA results shows that derived from ASSY consistent data, relative error ranging −2.76% 2.65%, which more accurate compared other criteria. obtained by declined increase n increased SDR. Therefore, solution-based paper an adequately suitable precise predictive tool for assessing failure pipes.
