Complex components in CIVA SHM

However, the “Specimen” panel in the CIVA GUI still only includes two geometries: Planar or Cylinder.

 

 

Indeed, these complex components are built from initial profiles of planar and tubular specimens.

The SHM module relies on a spectral 3D FEM method where the mesh is fully driven by the software. This mesh is first initiated from a simple geometric profile, before following the geometrical transformations applied to it in order to create the final complex geometry of the component with its adapted and structured mesh.

Therefore:

• From a planar component, it is in the “Curvature” panel that you can create specimens with irregular shapes, via the definition of a unique median profile, or through 2 different profiles applied on the upper and lower part of the plate, leading to a variable thickness.

• From a tubular component, it is also in the “Curvature” panel that you can create an elbow, generated from the initial cylinder.

• From a multilayers tubular or planar component, it is through the “Stiffener” panel that you can create a “Sleeve” on the specimen, by defining on which layer and along which length this sleeve is positioned.
