V shaped construction under plastic deformation
The V shaped is defined by an extrusion of a V shaped face.
Three planes are defined in the geometry: Pleft and Pright for applyind boundary conditions (dx=dy=dz=0) and Pforce for defining a prescribed displacement in y direction.
The definition of the geometry as well as the meshing is given in the Python input file.
In the geometry module of Salome select File --> Load Script (or ctrl T) and thereafter the file: Media:kw_gm_vshape.zip.
General procedure of the calculation
The general procedure of the calculation is as follows:
- read the mesh
- apply the non linear material properties of the construction
- define the boundary conditions
- define the maximum load, in this case a maximum displacement at the plane Pforce
- define 'time' and 'load' increments: here we define an increase multiplication factor for the loads from 0 to 1, then constant during a small time and decreasing from 1 to 0 again.
- perform the analysis
- define results in a med-file for Salome, in this case, displacements, vonMises and plastic stresses
- print results in a file, notably the displacements of the plane Pforce and its corresponding forces.
