Simulation of GRP Pipes Materials and Installations Parameters Experimentally and Using FEA
In this work, an analysis of GRP pipe installation is developed to study the interaction between a buried flexible pipe and surrounding supported soil. The results of the analysis are applied to computational model using FEA (Finite Element Analysis) to determine the pipe deformations at variable soil types around the pipe. Then, testing is done to compare FEA results with laboratory testing. The results obtained from simulation of deflection pattern for two different manufacturers are compared with ASTM 3839 D-88 for underground installation of flexible reinforced thermosetting resin pipes. The simulated model used two major manufacturers of buried pipes, allowing variation of soil stiffness and simulating realistic boundary conditions so in order that reliable deformations can be predicted. A semi-empirical methodology for the relationship for pipe in soil system for predication of the pipe and pipeline performance was developed in this work. The work developed a unified integrated approach for composite soil structure, which may be used by the designer, manufacturer and installers of GRP pipe.
