Análisis de integridad estructural de tuberías de material compuesto para el transporte de hidrocarburos por elementos finitos

Abstract

In this work, we performed a finite element analysis (FEA) to characterize the mechanical behavior of the composite pipe Fiberspar in order to investigate the structural integrity of composite pipes for crude oil transport in Colombia. Tests according to ASTM D2290 standard were performed in the laboratory to determine the tensile ultimate strength and compare the results with the numerical model. Failure criteria Tsai-Wu and Tsai-Hill were considered for the pipes working at different pressures, including operational pressure and, thus, the failure values and critical layers were identified.
