Analysis of Reinforced Thermoplastic Pipe (RTP) under Axial Loads
Reinforced thermoplastic pipe (RTP) is an innovative application in the oil & gas industry.The mechanical property of RTP under axial loads is a significant parameter for the popularization of RTP.This paper focuses on the experimental and numerical research on the behavior of RTP under axial loads.First,prototype tests,including axial tensile tests and compressive tests,are conducted; and then,a nonlinear finite element model employing solid elements and truss elements is created.In this ABAQUS model,the material nonlinearity is taken into account.The prototype tests reveal the fundamental mechanical properties of RTP under axial loads.The numerical models are validated against the generated experimental data,including load-extension relationship,load-shortening relationship,yielding load under tension,collapse load under compression,and failure mode.Close agreement can be found between the numerical results and the experimental results,so the finite element model in this paper can be regarde.
