FEM - FEA Analysis

Our highly qualified staff, use the most advanded design tools.

Structural elements workload behaviour knowledge represent a fundamental tool in designer's work. In the past to acquire these informations along the project phase, designers resorted almost entirely to dedicated manuals, mainly based on empirical-experimental formulas.

Production of a sample to stress before use was an indispensable step.
 

Recent times gave birth  to powerful tools able to satisfy the  growing need of necessary informations to improve products features. 'Virtual prototyping' has greatly reduced the need to resort to test sample, minimizing the time required to get an optimal product.
Thanks to finite elements analysis we are now able to create a subdivion of an object into a finite number of elements (mesh). It is so possible to bring back structural response determination to a numeric solution of a problem with a finite number of degrees of freedom.
This process allows to analyze  rather general problematic, possibly characterized by extremely complex geometries, for which analytical determination of the stress-strain response would be impossible.

Product optimization for material saving, therefore for customer saving, is of the utmost importance, always guaranteeing needed structural stability.

We realize static analysis at the most complex dynamic analysis using the most up to date calculation systems.

As an example we report an optimization for several depression walls calculated at an operating temperature of 250°C.

 

Step 1 : 3D Modeling

 

Constraints and stress agents study has been carefully made counting  all of the surrounding conditions needed to make the analyzed element as realistic as possible.

Customer initial requirements referred to a 5mm metal sheet. Optimizing the structure we evaluated the possibility to reduce thickness analyzing interaction between metal sheet and profile.

 

Step 2: Constraints and Loads Study

 
Customer initial requirement referred to a 6mm metal sheet. Optimizing the structure we evaluated the possibility to recduce thickness analysing interaction between metal sheet and profile.

 

Step 3 : Mesh e Results Analysis

 

Once we analyzed plate element stress, and finding that its stress and strains were greatly below the maximum allowable stress, we decide to parameterize the element and eveluate new ones with variable thickness.

Once we reached 3mm we got stress and strains values within allowable loads.

We evaluated strengthening profiles stress, which were optimized too, getting an additional weight reduction.
Strain was into Client's limits specification.
Strain has been analyzed in all of its points, carefully evaluating the more strained areas and doing a careful search for maximum reached strain.

 

This was just a little example of the analysis and optimizations available.

On the site are available in the "Developed Projects" and "Metallic Junctions Calculation" sections, analysis made to verify designed structures, to optimized them and sometimes to find better solutions to the existing ones. 

The finite elements method is a process of numerical analysis that allows to solve a wide class of engineering problems through discretization of any given structure. It represents nowadays the most powerful available tool in the structural analysis field.
