Low‐Velocity Lateral Impact Behavior of Water Pressurized uPVC Pipe: An Experimental and Numerical Analysis
Year: 2026
Type: article
Abstract: Impact loads are common worldwide and have varying degrees of severity. Different incidents, like the sudden impact of a car accident, have significant negative consequences for infrastructure, property, and human life. Numerous studies have been conducted over the past 50 years to investigate the behavior of different structural elements with various material properties under impact load. However, limited research has been conducted on the behavior of unplasticized polyvinyl chloride (uPVC) pipes that are subjected to impact. In this study, the locally developed testing setup was calibrated against a pressure gauge up to 4136.85 kPa, producing a near‐unity linear calibration coefficient of 0.99981 with an intercept of 13.494 kPa. The impact behavior of pressurized uPVC pipes under different support conditions and impactor dropping heights has been examined in this study. The pressurized pipe subjected to low‐velocity impact under constant internal pressure was modelled and analyzed using ABAQUS finite element analysis (FEA) software, with a constant internal pressure of 1378.9 kPa. The plastic deformation, as well as internal pressure fluctuations due to the impact of the hammer from different heights, was investigated. For the same drop height, the peak contact force was higher under the both‐end‐clamped condition. The contact period of the impactor is found to be higher than the positive pulse duration of internal pressure for both support conditions.
