Example 5: Ring under Forced Normal Displacement

General

• A ring is deformed due to the forced normal displacement.
   

• The distributions of displacement and stress are solved.
   

• Unless specified in the list below, the default conditions will be applied.

 Model

Two cylindrical solid bodies are created. The smaller cylinder is subtracted from the larger cylinder by boolean. As a result, a ring is created.

The inner face of the ring is set with the simple contact boundary condition.

Boundary Conditions

The normal displacement is set as follows:

Boundary Condition Name/Topology	Tab	Boundary Condition Type	Settings
DISP/Face	Mechanical	Normal Displacement	0.5X10-3 [m]

Results

The vectors of the displacement are shown below.

The inner side of the ring is displaced by 0.5 [mm] according to the boundary condition. The outer side is displaced less.

 

The vectors of the stress are shown below.

The tensile stress is exhibited in the circumferential direction, while the compressive stress is exhibited in the radial direction.
