Home / Examples / Stress Analysis [Galileo] / Example 45: The Mating of Connector
The mating of connector (2D) is analyzed.
The forces at the contact points between the plug and jack are solved.
Unless specified in the list below, the default conditions will be applied.
Results will vary depending on Femtet version and the PC environment.

The forced displacement is applied on the tail of the plug.
Two contactee surfaces are set on the inner surface of the jack and a contactor surface is set on the plug.
These are designated as a contact pair. The contact forces of contact pairs are acquired.

The material properties are based on the material DB.
8/WireBody is imprinted on the central axis of the plug. The wire body is allowed to move only in the X direction, as set in the boundary condition.

The distribution of the principal stress and the displacement when 50% of the defined load is applied are shown below.
The inner and outer areas of the jack exhibit tensile stress and compressive stress respectively.
The distribution of the principal stress and the displacement when 95% of the defined load is applied are shown below.
The Z component of the contact force is shown in the following graph.
The horizontal axis is steps. Displacement of Move is incremental over the steps.
Z components of the contact forces are generated in the opposite direction. The contact forces will come to zero after the plug fits into the cavity area of the jack.
