Finite Elemental Analysis

Finite elemental analysis refers to a new method of analyzing various parameters of a given structure such as the structural stiffness, thermal behavior and fluid flow interaction. The method is one of approximation and is undergoing tremendous development, with the introduction of newer algorithms and improved computing capability. Today’s industrial scenario demands that any technical solution provided should be minimal in terms of both the product development time and the cost. This has given rise to newer methods of analysis
which do not involve the production of a prototype. Owing to its sustained credibility, FEA has become one of the most widely used analysis tools. The first part of the assignment is concerned with a debate with regard to the merits
and demerits of empirical methods as against the FEA method. This section deals with an overview of the finite elemental method procedure and its related merits. The second section deals with assessing the structural behavior of the structure, in terms of stresses, displacement etc. The same parameters have been calculated manually and have been compared. The reason for discrepancies, if any has been assessed. The third section deals with conducting a thermal analysis of the pressure vessel. This is important, as it provides a clear understanding of the thermal stresses being generated and the temperature distribution. The outcomes of the assignment included getting a clear picture of the role of Finite elemental method in the product life cycle and understanding the significance of industry increasingly favoring the usage of tools such as finite elemental analysis over empirical approach. The procedures for determining the behavior of a structure were also learn.

The term empirical is defined as ‘Relying on or derived from observation or experiment. The origin of all forms of science can be traced to the keenness of man to understand his surroundings. Right from man’s understanding of the presence of light to the motion of the planets, human understanding has been based on his observation of the world around him. His understanding of the world has also been fueled by his attempts to mimic nature. Hence it can be safely said that the basis of all science has been human observation. Finite Elemental Method [FEM] is an approximation method used to determine the properties of a structure by solving suitable mathematical models in an iterative fashion. FEA refers to the analysis method, which employs FEM. ‘Checking the designed object for its functionality is called as engineering analysis.’[2] The process is more resource intensive in comparison with the former. However, with the aide of improved computing power, the application of FEM has seen immense growth. The term ‘properties’ used above refers generally to structural stiffness and thermal behavior. Thus it can be seen that it is a versatile tool.
