FEA is a computer application that uses numerical techniques to assess systems and structures. When subjected to thermal and structural loads, it accurately predicts how components will react. Instead of needing to construct the actual component, using a virtual computer-based model makes it easier to check the design and integrity of a component and pinpoint important areas for development. TEFUGEN offers exceptional FEA analysis and consultancy services to help with simulation-based structural and thermal evaluation of mechanical systems.

In the field of engineering design, Finite Element Analysis (FEA) has developed into a highly promising computer-aided engineering technique for modeling and analyzing structures with complex geometries and changeable material properties. It is commonly used during the design phase of a range of engineering fields, such as automotive, aerospace, power plants, and production engineering, to optimize products that increase performance.

◦ Minimize the product development cost
◦ Reduce the product lead time into the market
◦ Accurately predict components response to load
◦ Unlimited level of detail in the system
◦ Analyze difficult & dangerous experiments
◦ Easy repeatability of simulation

Linear Analysis:
The branch of FEA known as linear static analysis is most typically used to evaluate the structural and thermal performance of mechanical structures. The applied forces and displacements have a linear connection in linear static analysis. Actually, where stresses remain within the material's linear elastic range, this is relevant to all structural components. In a linear static analysis, the model's stiffness matrix is constant, and the solving time is quicker than in a nonlinear analysis of the identical model. In order to obtain an initial estimate, linear static analysis is usually used before performing a full nonlinear analysis.

Non Linear Analysis :
The analysis is referred to as nonlinear if the applied forces and displacements have a non - linear connection. Touch, material nonlinearities (elasto-plastic material) and geometric nonlinearities (large deformations) can all result in nonlinear effects. The stiffness matrix changes as the load is applied as a result of these factors. In contrast, the stiffness matrix in the linear static analysis was constant. In order to perform the nonlinear analysis, a different solving strategy and solver are required.

Static Analysis :
Static stress analysis is likely the most common type of structural analysis using the FE technique. Stress, strain, and deformation of a component or assembly can be assessed under various load scenarios to avoid expensive failures during the design stage.

Typically, structural loads consist of one or more of the following:

• Outside forces, like the clamping force in subsea connectors.
•  Surface loads, such as the pressure inside pressure vessels
• Body pressures (gravity, acceleration such as centrifugal force in rotating machines)

Dynamic Analysis :
The phrase "dynamic FEA" describes a number of dynamic simulation methods that can be used to analyze even complicated engineering systems. Dynamic analysis is used to design and analyze potential noise and vibration issues as well as to assess the effects of transient loads. As seasoned development engineers, we rarely end our involvement in a dynamic assessment with the analytical output. We frequently collaborate with customers to identify creative solutions that are practical and beneficial from a business standpoint.

Thermal Analysis :
Thermal analysis and FEA can be used to solve heat transmission in or between solids. Convection, conduction, and radiation are a few examples of heat transport mechanisms that can be calculated. However, the analyst directly estimates convection and radiation, not the FEA software. Heat transfer analysis with FEA is normally carried out when the heat convection coefficient can be assumed to be constant along the surface of the part or when the value is precisely known. FEA-based heat transfer analysis can also be used to determine structural stresses brought on by temperature gradients in the component, including thermal expansion.

Buckling Analysis:
By the use of buckling analysis, a structure's stability under compressive loading conditions is evaluated. To verify the stability of the construction, a weight-lifting device will need to be used under compressive loads. The kind of buckling analysis employed in FE analysis is called linear buckling analysis. A static structural study must be followed by a linear buckling analysis. The results of a linear buckling analysis are buckling load factors, which are scales of the loads employed in the static structural analysis. The structure will buckle when the aforementioned level of static loading is attained, according to the simulation's results. There are countless buckling load elements that might affect a building. Every load factor has a distinct instability pattern associated with it, similar to modal analysis. The bulk of us, however, are focused on the load factor that is the lowest.

Fatigue Analysis :
A fatigue analysis is used to determine if a structure would fail after a specific number of repeated loading and unloading, or "load cycles," as opposed to replicating one load cycle as in a static analysis.
