FEA ANALYSIS

Static FEA analysis

We can perform a linear or non-linear static FEA analysis for you. Your design is analyzed and its deformations are predicted using a finite element method. From the calculated displacement values ​​it is possible to derive the stresses experienced by the body. The results allow us to evaluate whether your design has been deformed. We can also see if critical stress conditions occur in your design.

Modal FEA analysis

A FEA modal analysis can help determine the natural frequencies of a structure as a result of vibrations. The results are important parameters to understand and model structures exposed to dynamic loads. A harmonic analysis can show the peak response of a system under a load in a particular frequency range. The purpose of this is to determine the natural frequencies of a structure with the associated deformations during free vibration.

Complex stress, strain and deflection calculation

Engineers are faced with many questions when designing structures, including the following:

• Can this bridge support enough weight?
• Does my design meet the strength requirements?
• Which material should I use?

These questions can be answered by applying a finite element method. One of the reasons performing an FEA analysis helps engineers is that it allows them to predict performance. Instead of physically test every possible combination of materials and construction methods, engineers can simply have it done by a computer.

Performing an FEA analysis allows engineers to develop plans without worrying about testing them. It’s easier to visualize problems three-dimensionally and make changes while tracking results in real time.

An additional advantage of analysis is that it provides designers with valuable information related to safety. By simulating failure scenarios in advance, engineers can ensure that their design does not fail.

When do you use a FEA analysis?

A FEA analysis is applied when the design cannot be calculated analytically due to its complexity. It often happens that a design has complex geometries that cannot be calculated. A simulation must be performed, otherwise the analytical calculation will take too much time. In addition, simulations are performed to reduce production costs and reduce prototyping during the design phase.

Who uses a FEA analysis?

Many companies use finite element method software to optimize product designs. Sometimes companies hire consultancies to analyze designs and make recommendations based on the findings. These professionals include civil engineers, mechanical engineers, structural engineers, etc.

Industries that often use a FEA analysis are aerospace, automotive, chemical plants, pharmaceutical companies, shipbuilding, mechanical engineering, civil industry and water treatment companies. Government agencies also conduct extensive studies using a FEA analysis.

Advantages and disadvantages FEA analysis

There are advantages and disadvantages associated with performing a FEA analysis. The advantage is that you get results quickly. Engineers can instantly see how changing variables affect the overall results. In addition, a simulation saves costs through shorter development cycles.

A FEA analysis also has disadvantages. A FEA analysis only gives an approximation of reality and gives you an estimate of the stress distributions. The finite element method only works on mathematical approximations. Errors quickly occur that depend on factors such as material properties, boundary conditions and MESH refinement. Another disadvantage is that a simulation requires a lot of expertise and cannot be performed by everyone.
