Resumo
The industry needs predictability to work on a large scale without complications, only this way you can ensure your productivity. The piping flexibility analysis provides a prediction of future problems and proposes applicable solutions, with the objective of preventing pipes to suffer collapses, that can impact the production process and costs, and provide safety to workers and the environment, while avoid leaks and possible contamination. The aim of this study is analyse the flexibility of industrial piping through the finite elements and photoelasticity methods. For stresses analysis, using a computerized body of proof, it`s possible to find, through finite elements and photoelasticity`s practical project, the values of the stresses and the places where they are being applied. To guarantee that the computerized and practical models are consistent with reality, a mathematical model, already tested and proved, will also be implemented and compared to the others, so there are evidences that all models used are really reliable and can be used in large-scale industrial projects, with complex studies. A comparison of a mathematical model through balanced guided beam, a finite elements model using the software ANSYS® and a photoelasticity of a resin pipe will show that the method with better applicability in industries is the computational, showing trustable stress, reaction and deformation values as well as a detailed visualization of them distribution along the object of study.
