Finite volume method and multigrid acceleration in modelling of rapid crack propagation in full-scale pipe test

摘要

Rapid Crack propagation (RCP) along pressu- rised plastic pipes is by far the most dangerous pipe failure mode. Despite the economic benefits offered by increasing pipe size and operating pressure, both strategies increase the risk and the potential consequences of RCP. It is therefore extremely important to account for RCP in es- tablishing the safe operational conditions. Combined experimental-numerical study is the only Reliable approach of addressing the problem, and extensive Research is undertaken by various fracture groups (e.g. Southwest research institute -USA, Imperial College- UK).
