# Finite element analysis2 - Essay Example

## Extract of sampleFinite element analysis2

It can be used to analyze either small or large-scale deflection under loading or applied displacement. It and can analyze determine elastic deformation, or "permanently bent out of shape"permanent plastic deformation. The Widespread use of personal and mainframe computers in the second half of the 20th century catalyzed applications involving FEA is required because ofdue to the astronomical number of calculations needed to analyze analyse a large structure. Today, FEA is an integral part of nearly all design and development projects.
As mentioned, thisThis report has been complied compiled to document the results of of tensile testing on a buckle connection simulated by the Finite finite Element element Analysis analysisof a buckle connection. The function objective of the FE Analysisanalysis was to obtain determine the maximum stress max of the buckle connection, which is based must be designed to resist withstand a 450 Kg kg of tensile loadon, as written in assignment.
It is also important to note that although the method of finite elements is a powerful analysis tool that is widely applied, it is still simply an approximate numerical estimate. In other words, although results accurate enough for engineering purposes are obtainable via precise modelling and adequate numbers of elements, exact solutions are highly unlikely.The buckle connection was designed to be made from Stainless Steel plate. A comprehensive set of properties for the specified material is shown in table 1

Material properties of Stainless Steel

The next section discusses the assumptions made in preparing for the analysis; then the modelling is described. The subsequent sections include the finite element analysis calculations, a discussion and then conclusions and recommendations are provided.

ASSUMPTIONSAssumptions:

As in any engineering problem, the first step is to develop a list of assumptions which will be used as guidelines to help bound the physical problem. Assumptions necessary for finite element analysis are divided into four categories: geometry, properties, mesh, and boundary conditions.
In the begging of doing this report in FEA Package there are numbers of assumptions were made which give create more imaginations as key in testing any design before test it in real life. First, in terms of the geometry, it is assumed that the drawings provided are accurate representations of the buckle and also that the determination of pass/fail judgement for the part is based simply on the tensile test of the flat plate of the buckle and that no other variations in the standard belt assembly come into play, e.g. length of the belt, etc. Shell elements are utilized and it is assumed that they can adequately model the part. Thickness of the buckle was assumed to be constant across the part and the element type chosen was selected in part because its input data allows incorporation of thickness values. ly
Material properties were the next consideration whereby it was assumed that all material properties supplied provided by the designerin the problem statement were correct accurate and provided a true representation of the material specifiedto be analysed. . Ambient temperature and pressure are assumed to have no effect on the analysis results. Another basic assumption made was that the material was homogeneous and isotropic and had no discontinuities or residual ...Show more

## Summary

The Finite finite Element element Analysis method was first introduced in the 1950's and has been continually developed ever sincesince then for solving complicated mathematical problems. Its applications range from stress analysis and heat conduction to fluid flow, lubrication, electric and magnetic fields…

However, the use of the finite study has yielded theoretical convergence normally based on the numerical solutions from the models selected. The study of convergence is done via the use of the numerical results as the number of elements increase. The present paper is based on providing the convergence of various elements with different number of nodes.
