Summary
This report details the structural integrity of a stainless steel buckle from a standard lap belt used in passenger aircrafts. The assembly has been designed to withstand a 450 kg tensile load. In order to be released into the market it must be confirmed that the material of the buckle does not exceed its yield strength and no significant distortions occur…

The finite element method (FEM) is a numerical procedure used for finding approximate solutions of partial differential equations (PDE). A partial differential equation is a differential equation containing derivatives involving two or more independent variables. In engineering science, many phenomena are described by partial differential equations, such as displacement or temperature as a function of time and space. Problems involving PDEs are usually too complicated to be solved by classical analytical methods. Solving PDEs with the method of finite elements is possible today due to rapid solving capabilities of computers. Finite element analysis (FEA), originally used to solve stress analysis problems, is an approach which is used today in many branches of engineering including heat transfer and fluid flow.
The material of the part is 2.5 mm stainless steel plate with a Young's modulus of elasticity of 206 GN/m2, a Poison's ratio of 0.3, and a yield strength of 580 MN/m2. It is assumed that the material has linear elastic properties and is both homogeneous and isotropic (although in reality this is not exactly true for cold-rolled sheets where grain orientation may vary). In addition, it was assumed that no discontinuities or residual stresses are originally present in the material due to manufacturing processes such as forging, rolling and welding.

The thickness of the part is assumed constant and is believed to be small enough compared to its width such that shell elements can be used for adequate accuracy in modelling. Figure 1 shows the buckle modelled in ANSYS. The part is symmetric in two directions and has been separated in the model for simplification. Figure 2 shows the original drawing of the buckle and its symmetry. It is assumed that the geometry of the part is adequately represented by the finite element model developed. Displacements are expected to be relatively small such that a linear approximation will be valid.

The solution of a finite element analysis is only so good as the quality of the mesh. The smaller the element size, the better the mesh should represent the geometry of the part. For this analysis, two mesh sizes were used: a smaller one where the highest stress concentrations were expected, and a larger one throughout the remainder of the model. The curved sections of the two slots were expected to receive the greatest stresses and were thus meshed with a value of 0.25, while the remained of the buckle was modelled with a 0.51 mesh size. The element type used was the PLANE82, which is a 2D structural solid element with eight nodes. Eight-noded elements are more accurate for modelling curved boundaries. The PLANE 82 shell element type also allowed for a thickness value in its input properties thus facilitating a 2D problem.

...will be read and reflected in this important part of the report to understand the phenomenon of boron added steel under high temperature process (German, 1990) EFFECTS OF BORON ADDITION IN STEEL Boron is a good element when it gets added in steel because it provides more hardness to the steel, as shown in the experiment conducted in class and the analysis that has been explain in the earlier part of this report. When boron is added to any type of low grade steel, it gets more hard than usual. The products of such mixture, the steel, are more hard and high quality in nature. These steels...

### Finite Element Analysis

...Introduction The finite element method is generally employed by the engineers, scientists, and mathematicians to derive solutions for differential equations. The scientists and engineers have been able to find solution of several physical and non-physical problems through finite element analysis. The finite element method is applicable on solids; liquids, plasma and gaseous substances, and problems related to soil mechanics, electromagnetism and dynamics can be traced through this technique. This exercise is based upon the theory which sub-divides a complicated domain into "series of smaller regions in which the differential equations are approximately solved; by assembling the set of equations for each region, the behaviour over... the...

...What is Finite Element Analysis' Finite element analysis is a tool used in engineering to determine the physical effects a given set of boundary conditions will have on a part. Boundary conditions can be forces, temperatures, hydrostatic pressures, centrifugal pressures, torques, and displacements. The basic theory of finite element analysis is the same regardless of the type of analysis being done. The geometry being modeled will always be divided up into smaller divisions known as elements and the elements are connected together to form...

### Finite element method

...WARNING: THE COMPUTED ANSWER MAYBE WRONG The advantages of finite element programs are so extensive that they overshadow the limitations of these programs and the users never consider the limitations. Analytic methods are not universally applicable because of their reliance on the theories which are derived on the basis of certain assumptions. As a result various features of physical behaviour are sometimes not undertaken in the analysis. A computer program cannot be free from errors because of the large amount of coding associated with it. Large computer programs involve a lot of computing and a number of computational paths and thus it is not possible for the programmer to check each...

Objectives of the project Finite element analysis has been used to build and to improve very many structures. However, this is only productive and successful when there are no mistakes in finite element modeling. Otherwise, any single mistake can result to dramatic, grave consequences.
