Bracing with ribs
2. Model/Geometry
The first step is to create the model of the plate, which we can simply do in the Creo Parametric program. With this program was the fastest and easiest way to create the model. The finished geometry (Creo) and the meshed model (Gmsh):


3. Materials and boundary conditions
3.1. Materials
The beam is made of steel, so we need to use the following data:

E = 210 GPa → 210e3 N/mm^{2}

nu = 0.3

rho = 7800 kg/m^{3} → 7800e9 kg/mm^{3}
"Materials":
{
"omega":
{
"E":"210e3", // N/mm^2
"nu":"0.4", //
"rho":"7800e9" // kg/mm^3
}
},
3.2. Boundary conditions
The plate is fixed with three screws (yellow → named fixed
). The force is applied, where are the other three srews (green → named load
).
