SSLV100 - Hollow Cylindre in plane deformations
Summary:
This test makes it possible to validate the elements of plane deformation on the following functionalities:
· pressure distributed,
· stamp rigidity,
· imposed displacements:
- by
ddl,
-
by face of element.
It includes/understands 4 modelings.
The 3 first correspond to elements of the different type (linear and quadratic).
The last validates the displacements imposed by face (blocking of the normal component).
