Purposes of the mechanical computation

We guide you through the implementation of your computation process so that you are able to:

  • Ensure a design satisfying the current norms;
  • Estimate the mechanical strength of your system and carry out iterations on the design to optimise it (mass or strength improvement, size reduction…) before producing a prototype;
  • Define the lifespan in time as a function of the number of load cycles imposed on your structure (uniaxial or multiaxial fatigue analysis).

The steps of modelling

Depending on the complexity of your system, we can either use an approach with the strength of materials or, whenever it is necessary, turn to a modelling by Finite Element Method. In this case, we are able to use Ansys, as well as Nastran or Code_Aster. Then, a structure modelling will take place as follows:

1 - Design/Geometry

Defining the concept design or simplifying the CAD of your design office.

2 - Materials

Defining the materials characteristics of the different components of this system (isotropic, anisotropic, orthotropic characteristics).

3 - Connections

Defining the connections properties of these components (weld joint/belt, bolted assemblies, gluing, rivets…)

4 - Loads

Defining the environment (boundary values) and the loads that the structure will undergo: pressure, stress, vibratory levels, acceleration, forced movement, earthquake, impacts, etc.


Types of analysis

Whatever your design issue is (seismic, pressure strength, micromechanical, dynamic…), we will submit different support solutions all along your project.
