Finite Element Analysis (FEA)
Finite Element Analysis (FEA) is a computer simulation technique used in engineering to analyze how a product withstands loads, heat, fluid flow, and other physical effects.
Some key concepts about FEA:
- The product geometry is divided into small pieces called elements. Elements have nodes where the pieces connect.
- The properties of the elements and loads applied are defined based on real-world conditions.
- A mesh is created by connecting the elements into a network. Finer meshes provide more accuracy.
- An equation solver calculates the effects of the applied loads on each node of the mesh.
- The node displacements, element stresses, strains, and other outputs are determined for the entire model.
- The results can be visualized through contour plots, vector plots, animations, etc.
Common Types of Finite Element Analysis
- Static structural analysis – Determines deformations and stresses from steady loads.
- Thermal analysis – Calculates temperatures and heat transfer.
- Modal analysis – Finds natural frequencies and vibration modes.
- Nonlinear analysis – Accounts for large deflections, plasticity, contact, etc.
- Fatigue analysis – Predicts fatigue life and crack propagation.
- Fracture analysis – Deals with – The initiation, propagation, and progression of cracks until final failure occurs.
- Fluid flow analysis – Models fluid dynamics and pressures.
- Shock & impact analysis – Determine how a product or system will withstand sudden accelerations, decelerations, shock, and impacts.
- Acoustic & noise analysis – It allows engineers to simulate how noise is generated within a system from vibrations and fluid flow.
- Buckling, post-buckling & collapse analysis – It determines the loads at which structures become unstable and collapse due to buckling.
- Multiphysics Simulations
- Composite Modelling and Analysis
- Fluid-Structure Interaction (FSI)
Benefits of Finite Element Analysis
- Identifying weak spots and failures before manufacturing
- Optimizing designs for lighter weight, higher strength, and longer life
- Reducing physical testing needs by using virtual prototypes
- Considering many “what if” scenarios to improve designs
- Gaining insight that can be difficult or expensive to obtain otherwise
Finite Element Analysis uses the mechanics of continua to obtain approximate solutions to problems that are difficult to solve using analytical methods alone. It is a useful engineering analysis technique that provides insight to improve product designs.
