Shell analysis

1. Dynamic shell analysis
   * Dynamics of shell.
   Contrib:KeesWouters/shell/platedynamics
   
   • Use of shell coque_3d elements
     
   • This contribution is an simple example of a dynamic plate modelled by shell -coqued_3d- elements
     
     • key words:
       
       • use of Salome: definition of geometry, mesh - export of mesh
         
       • use of ASTK
         
       • conversion of tria6, quad8 to tria7 and quad9 (note the difference between CAster vs9 and vs10)
         
       • projection of results of quad9 and tria7 to quad8 and tria6 for coque_3d elements
         
       • definition of:
         
         • shell characteristics: epais - thickness, excentrement - eccentricity, local coordinate system: vecteur, angl_rep
           
         • mass, stiffnes matrix and range of dof, NUME_DDL
           
         • definition of eigenvalue extraction -
           
       • print mass table
         
2. Static analysis of shell construction
   * Contribution in collaboration with Brigde.
   Concrete shell with several partitions loaded by pressure.
   Extraction of displacement and stresses.
   Contrib:KeesWouters/shell/static
3. Static shell analysis - generation of tables
   * Contribution in collaboration with Brigde.
   Concrete shell with several partitions loaded by pressure.
   Focus on extraction of minimum and maximum displacements, forces and moments and stresses.
   Contrib:KeesWouters/shell/tables
4. Plot results of shell COQUE_3D calculations
   * The centre node of COQUE-3D elements is a headache in postpro.
   Projecting the results to a mesh without centre nodes.
   Presented on a plate with four holes.
   Focus on displacements and stresses.
