A block pressed onto a plate is analyzed. The contact is with friction.
The deformation due to the friction can be observed.
Unless specified in the list below, the default conditions will be applied.

The displacement diagram is shown below. The color gradation contour indicates the X displacement.
The lower part of Block is dragged to the negative X direction.
Vectors of the principal stress are shown below.
The minimum principal stress is inclined towards the friction direction.
The figure below is when the friction is nil.
The minimum principal stress is not inclined because there is no friction.
The dragging is not observed either.
