Finite Element Analysis

Finite Element Analysis Explained Simply

You might have come across the term ‘finite element analysis’ many times when speaking with engineers. You may even vaguely understand what finite element analysis is and how it works to deliver dynamic solutions to your business. However, if you have no idea what those words mean, don’t worry. At Ettol, we’re proud of our commitment to being ahead of the game in the engineering industry. We’re always on the lookout for new technologies that will streamline our processes and deliver our clients the most accurate, detailed results possible. We have plenty of experience in working with complex computer-aided engineering (CAE) software that conducts finite element analysis services. So, we’ll walk you through the basics of dynamic finite element analysis, so next time you’re discussing the topic with one of Ettol’s engineers, you’ll be more in the know.

What Is Finite Element Analysis?

When engineers conduct a finite element analysis, they are using CAE technology to predict how a product will react to force, vibration, fluid flow, heat, and other physical effects in the real world. It allows us to accurately predict whether or not a product will break, wear out, or work the way we’ve designed it. 

How Does Finite Element Analysis Work?

This is where our explanation becomes a little bit more complicated. Finite element analysis works by taking a problem and breaking it down into smaller, more manageable problems. These micro-problems (also called elements) are then solved and reassembled into the bigger problem which is now, by extension, also solved. We do this by creating a representative model of your product that we can then use to analyse how the product will react when faced with various external conditions. To build a model, we first need to get information about the product. 

  • Basic geometry. Geometry is critical in conducting a finite element analysis, and it refers to the general shapes that make up the product. For example, the leg of a table may be a cylindrical shape. 
  • Definite loads and constraints. Loads are the weight or heat influxes your product will experience, and the constraints limit how your product can move.
  • Mesh. The term ‘mesh’ refers to the material that fills the geometry of your product. Mesh can be steel, wood, rubber, sandstone, or any other material of which you can think. In our example of a table leg, you may choose wood as your mesh, or you may choose steel. You wouldn’t select rubber, as the table leg would then bend exactly like rubber.  
  • Elements. Within the mesh, there are elements. Elements can be 1D, 2D, or 3D depending on the product you’re analysing. 

After all this information has been put into the computer, we can go about analysing the outcomes. We’ll be able to see the stressors, the energy content in strain, the deformed shape, and plenty of other useful information that we can then use to assess how your product will function under specific conditions.

The Benefits of Finite Element Analyses in Australia

Finite element analysis consulting can be an invaluable tool depending on your industry. If you need your products to undergo rigorous testing and simulations, it may be well worth your time to contact Ettol about our finite element analysis services.

  • Create endless prototypes and simulations. Gone are the days of investing hundreds of thousands of dollars into real-life prototypes built for destruction. With finite element analysis, you can run as many simulations as you’d like, as all your models and simulations are digital. You can make any minor alterations to your design and see how they will react to external forces quickly and efficiently.
  • Identify design issues early. With finite element analysis, you can get information on any design errors and problems before you invest in production costs. You can address these issues by altering your design digitally and retesting, thereby ensuring your product passes all finite element analysis simulations before manufacturing.
  • Saves time and money. Ettol’s finite element analysis services will save you countless hours and thousands of dollars on prototypes and physical testing by providing you with accurate, real-time data.
