Thermal mechanically Coupled Analysis of Lining Process

摘要

In this study, we consider how to reduce the remained PVC pipe under various heating conditions in lining process by finite element method (FEM), and simulate the deformation and adhesion process of PVC pipe and establish the numerical analysis model that can be explained resin behavior. PVC is representative linear viscoelasticity, so we use viscoelastic-governing equations to represent actual resin behavior. They enable us to evaluate stress and deformation behavior correctly. We also apply these analysis models to other environment friendly materials.
