The simplest case in 3D space would be node to triangular facet contact.
In this example, we show how to model 3D contact problems by using both penalty function method and Lagrangian multiplier method.
The model scripts can be .
The contact itself does not need to be defined on any discrete surfaces of elements. Instead, the facet is always formulated by the given three nodes. Thus, contacts can be defined on, for examples, plate/shell surfaces, cube/tetrahedron surfaces, or even three nodes only.
Here we define a square flat shell with one edge clamped.
A 3D beam cantilever beam is defined on top of the shell.
Once the deformed free end reaches the shell, contact occurs.
The facet is defined by nodes 3, 6 and 10. The slave node is 2.
After configuring analysis, it can be performed.
The animation can be shown as follows.
