NUMERIC SIMULATION OF MATERIAL BEHAVIOUR IN MANDREL BENDING
Abstract: Finite Element Method (FEM) is the most efficient method of numerical analysis in engineering. Simplicity of principles and basic concepts of the finite element method is a significant advantage for anybody using this method. FEM has continuously been developed as a numerical calculus method in a broad range of domains and applications of the deformable body mechanics using the displacement method, beginning with the need for instruments able to describe complex mechanical system, and currently reaching a level of development which allows for solving differential equations systems with complex derivatives.
Main advantages of FEM include: flexibility, possibility of modelling bodies which are physically not homogenous, as well as easy implementation in general calculus programs. The object of present paper is to extend the understanding of phenomena occurring in large diameter pipe bending using the mandrel pulling method.
Keywords: bends, connections, bending, numerical simulation, finite elements.
