Translations:FEM Shear of a Composite Block/26/en

To prevent rigid body motion in the plane of sliding, three independent degrees of freedom need to be eliminated. To achieve this, one vertex in the plane of sliding is constrained in x and y direction (eliminating 2 degrees of freedom) and one vertex is fixed in the x direction (eliminating the last degree of freedom). For this purpose two additional FemConstraintDisplacement objects are created and the result is shown below.
