Abstract:

Until recently, most design tasks were able to be solved with the help of computational tools like Finite Element Analysis. Engineers have adopted FEA as a design tool, hence it has become necessary to know its merits, drawbacks and methods to overcome these drawbacks. FEA is simple, because it assumes many properties of a system (like behaviour of materials, boundary conditions etc.) to be linear. These assumptions of linearity are plausible under certain conditions. However, nature is not always linear. Today, engineers have to consider non-linearity for designing certain parts, invalidating the assumptions of FEA for their design.This paper discusses the need, types and applications of non-linear Finite Element Method. This is followed by studying the simulation of few components, explaining the need and type of non-linearity in each case. The simulation is performed using computational methods on ANSYS workbench.
