Basic Concept of Finite Element Analysis You Need to Know

Finite Element Analysis (FEA) is basically a numerical method required for finding out the solutions in mathematical physics and engineering. It is ideal for the problems having complicated loadings, geometries and material properties. Thereof, it has been the substantial value to most of the product design process.

What could be the need of Finite Element Analysis?

As it bestows both significant and design guidance together, it would be helpful in creating the best products for use. Here, we are citing some of the important benefits of using FEA.

• Calculate the performance for future use.
• Anticipate the possible failure with predictable abuse.
• Does the proper evaluation and rectify the observed failure.
• Straighten out the performance and safety of a design.
• Perk up the cost/weight of a design.
• Discover creative and new ideas.
• Taking insight of design concepts or directions.
• Offering accuracy in the complex designing.

The basic concepts everyone should know regarding FEA

Zeal CAD is a steadfast organization who is engaged in offering FEA services, cad services, drafting services and much more. You can trust on us to get the quality results. In this blog, we are talking about the basic concept that everyone should know while practicing Finite Element Analysis.

The very basic approach of this study is that the force is determined by measuring the displacement. The process of FEA entailed the process that followed as step-by-step.

Step 1: Creating the Geometry

Step 2: Assigning material properties

Step 3: Create meshing

Step 4: Applying loads and constraints

Step 5: Reviewing the results

Modeling idealization

Firstly coming in this, it comprises of primary 3D stimulation including, beam stimulation, symmetry & anti-symmetry, plate or shell models and 3D solids. For the modeling idealization, we have to understand all.

Idealizations and Element types

There are nodes and elements present in creating the finite element mesh. Nodes are in general available as points in 3D space while the elements are volumes or areas that are defined by nodes.

Material properties

For the linear analysis, there are basically three choices available: Orthotropic, Isotropic and Anisotropic. Some conditions occur in which nonlinear materials are used for the process.

Talking about the geometry

In any analysis model, the geometry can be added by two methods:

• Use the CAD services for creating the geometry.
• Import or open an existing CAD model.

Basics related to meshing

Not that all the meshes are not the best meshes. The question arises, how to find it?

• Note that, if your mesh is too coarse, then your model will be too stiff.
• The most of impact can occur by local stresses.
• Convergence is regarded as the process practicing element size reduction and ensures the proper response.
