Polyvinyl Chloride (PVC) is used in various applications with the material being a polymer, and is growing as the use of polymers to substitute other materials in various application areas. One of the major aspects related to this growth is the low cost, relative to the use of traditional materials. However the mechanical properties of polymers differ considerably from metallic or ceramic materials, they exhibit very different behavior when subjected to stresses or deformations. A polymer used for a considerable time is Polyvinyl Chloride (PVC), mainly as pipes in building installations. However, these tubes are used almost exclusively for the transport of fluids, especially cold water. Trying to evaluate the use of these PVC pipes two different periods of manufacture and structural components, this paper presents computer simulations of these situations bending, subjected to different requests of force through the Finite Element Method (FEM). Because of the lack of material parameters, several experimental tests were performed in a traction machine, using PVC pipe samples used in building systems of cold water. Obtained the actual parameters displays a comparison of the experimental results and the simulation by finite element method (FEM), using CAD and CAE software tools in bending situations. Faced with this scenario is analyzed how sturdy are the PVC pipes to bending, for aiding from the understanding of mechanical behavior of a material the use of low cost, easy formability, compared to its restrictions be applied to other business scenarios
