In order to study the compressive behavior of flexible pipes, a nonlinear Finite Element model was developed. This fully tridimensional model recreates a five layer flexible pipe with two tensile armor layers, an external polymeric sheath, an orthotropic high strength tape and a rigid inner nucleus. The friction coefficient is known as a key parameter in determining the instability response of flexible pipes tensile armor. Since the featured model includes all nonlinear frictional contacts between the layers, it has been used to conduct several experiments in order to investigate its influence on the response. This article includes a description of the Finite Element Model itself and a case study where the friction between the layers of the pipe is changed. The procedure of this analysis is here described, along with the results.
