Abstract

In the present paper, numerical nonlinear models for the mechanical behavior of metal-reinforced plastic pipes (MRP) in destructive tests are developed to analyze the stress-strain state (SSS) in such pipes during loading. The paper focuses on the nonlinear response of composite pipes consisting of two plastic layers and a steel tube layer. A parametric analysis regarding the internal pressure and external loading has been conducted, using the DOE method. Moreover, the effect of pipe radius on the mechanical response has been studied through three different case studies. For the computation of the stresses and displacements the general finite element software ANSYS is used.
