class=\"ez-toc-section-end\"><\/span><\/h2>\r\nFEA is actually a numerical method which is used in solving engineering problems as well as scientific problems. Using this technique, a complicated system or structure is divided into smaller, more manageable components called finite elements. These components are generally joined at nodes. FEA applies mathematical equations, simulating how the structure behaves when it is subjected to different conditions (loads and temperatures etc.), using one or more finite elements.\r\n\r\nThis software basically brings the mechanics and materials science information together to predict how a structure will behave under certain scenarios. The findings afford valuable data for stress analysis, deformation and such other parameters which enable the engineers to take informed decisions regarding design &amp; performance.\r\n<h2><span class=\"ez-toc-section\" id=\"How_Does_Finite_Element_Analysis_Work\"><\/span>How Does Finite Element Analysis Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\nThere are a few key steps in the FEA process:\r\n<h3><span class=\"ez-toc-section\" id=\"Pre-Processing\"><\/span>Pre-Processing:<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<ul>\r\n \t<li><strong>Model Creation:<\/strong> The first step consists of creating a digital model corresponding to the structure or system under analysis. This will consist of geometry, material details and border sections.<\/li>\r\n \t<li><strong>Meshing:<\/strong> It is the process of breaking down a model into parts. Each element defines its geometry (i.e., tetrahedral, hexahedral) and its corner nodes. The quality of the mesh considerably impacts the accuracy of the results.<\/li>\r\n<\/ul>\r\n<h3><span class=\"ez-toc-section\" id=\"Solution\"><\/span>Solution:<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<ul>\r\n \t<li><strong>Applying Loads and Boundary Conditions:<\/strong> The model is then subject to external forces, temperatures and boundary conditions. These are more real-world like scenarios.<\/li>\r\n \t<li><strong>Solving the System of Equations:<\/strong> The FEA software solves the system of linear (or nonlinear) equations defining each element. It is the step of how the entire structure reacts, through complex mathematical analysis.<\/li>\r\n<\/ul>\r\n<h3><span class=\"ez-toc-section\" id=\"Post-Processing\"><\/span>Post-Processing:<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<ul>\r\n \t<li><strong>Result Visualization:<\/strong> Once they arrive at the solution, they simply plot a graphical representation of their outcome. This allows engineers to see how stress distributions, deformations and other key features change throughout the life of a structure.<\/li>\r\n \t<li><strong>Interpretation:<\/strong> Researchers use a comprehensive analysis of the results to interpret how well the structure performs and to detect unresolved issues. The engineers use that data to carry out design improvements or validations required by the final specifications.<\/li>\r\n<\/ul>\r\n<h2><span class=\"ez-toc-section\" id=\"Key_Concepts_in_Finite_Element_Analysis\"><\/span>Key Concepts in Finite Element Analysis<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<h3><span class=\"ez-toc-section\" id=\"Mesh_Quality\"><\/span>Mesh Quality:<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<ul>\r\n \t<li><strong>Element Types:<\/strong> Elements such as triangular and quadrilateral shapes are based on the geometry of the model. The element type you are using also has an impact on the accuracy and efficiency of your analysis.<\/li>\r\n \t<li><strong>Refinement:<\/strong> This requires special interpretation of the result, as finer mesh (more elements) allow more accuracy while excessive refinements can consume a great amount of computing power. In general, engineers apply mesh refinement to high-stress regions or locations with complex geometry.<\/li>\r\n<\/ul>\r\n<h3><span class=\"ez-toc-section\" id=\"Material_Properties\"><\/span>Material Properties:<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<ul>\r\n \t<li><strong>Elasticity:<\/strong> Most of the time, engineers consider materials to be linear elastic (as soon as they remove the load, the material regains its initial shape). However, they can also model nonlinear materials.<\/li>\r\n \t<li><strong>Thermal Properties:<\/strong> When performing a thermal analysis, we will include the material properties such as thermal conductivity and specific heat.<\/li>\r\n<\/ul>\r\n<h3><span class=\"ez-toc-section\" id=\"Boundary_Conditions\"><\/span>Boundary Conditions:<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<ul>\r\n \t<li><strong>Fixed Supports:<\/strong> These is the main points or regions on which the structure is fix.<\/li>\r\n \t<li><strong>Load Applications:<\/strong> There are various ways to induce loads such as forces, pressures or temperatures.<\/li>\r\n<\/ul>\r\n<h3><span class=\"ez-toc-section\" id=\"Solution_Methods\"><\/span>Solution Methods:<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<ul>\r\n \t<li><strong>Linear Analysis:<\/strong> When material and structural response is linear Appropriate for problems that have little deformation and linear elasticity properties.<\/li>\r\n \t<li><strong>Nonlinear Analysis:<\/strong> It is use when dealing with large deformations, nonlinear material properties, or complex boundary conditions.<\/li>\r\n<\/ul>\r\n<h2><span class=\"ez-toc-section\" id=\"Applications_of_Finite_Element_Analysis\"><\/span>Applications of Finite Element Analysis<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\nFEA is a national practice common to many industries around the world for handling some of today&#8217;s most challenging engineering problems.
