Static analysis of a shell construction

[ .... under construction .... ]

This contribution is in close cooperation with Bridge.

In this example the following items are discussed:

preproccesing:
definition of geometry in Salome
partitioning of the geometry and groups
meshing of the geometry
definition of the groups
(maybe: python script which makes editing much easier ...)

static analysis with pressure or force applied on a group or nodes

postprocessing:
viewing displacement in Salome
determination of stresses

interface ASTK

Definition of the geometry

planar shell Geometry:

L = 11.38 m
Thickness = 0.55 m

Loads:
[type] [group] [value]

Presure1 (Fbot) = 29.5e3 Pa
Presure2 (Fmain)= 25.8e3 Pa
Presure3 (Ftop) = 24.3e3 Pa
Presure4 (Fcentre1,Fcentre2)= 182.6e3 Pa

Boundary conditions:

Lbot (DX=0.0, DY=0.0, DZ=0.0)
Ltop (DZ=0.0)

Material:
Concrete

E = 32e9 Pa
Nu = 0.2

Create all points and lines using: [New Entity]->[Basic}->[Point] and [New Entity]->[Basic]->[Line]
:

The coordinates are:

P1 = geompy.MakeVertex(  0.000,  0.00, 0.00) 
P2 = geompy.MakeVertex( 11.380,  0.00, 0.00)
P3 = geompy.MakeVertex(  0.433,  2.25, 0.00)
P4 = geompy.MakeVertex( 11.813,  2.25, 0.00)
P5 = geompy.MakeVertex(  1.875,  9.75, 0.00)
P6 = geompy.MakeVertex( 13.255,  9.75, 0.00)
P7 = geompy.MakeVertex(  2.010, 10.45, 0.00)
P8 = geompy.MakeVertex( 13.390, 10.45, 0.00)

P9 = geompy.MakeVertex(  5.300,  5.72, 0.00)
