Question

How can I additionally model welds for the connection of two surfaces with a contact solid?

Answer

Since the boundary surfaces of contact solids can only be of the Null Surface type, it is necessary to model additional surfaces with a section. The following is an example for this.

There is a reinforcement of a plate with an additional plate. Both plates are connected by means of a contact solid:

In order to simulate a weld, borders are required on both plates:

You can simply create the bottom border by inserting a new rectangular surface. In this case, the program asks whether the surface should be integrated into the base surface, which must be confirmed by clicking Yes. There are then two openings in the bottom surface; one in the outermost surface where lies the surface for the border, and another in the surface for the border where lies the bottom surface of the contact solid:

For the upper border, it is also necessary to create a new surface, and the opening to the upper surface of the contact solid must be inserted manually:

After creating the borders, you can insert the actual surfaces for the weld:

If the reinforcing plate is subjected to tension now, the modeled weld transfers the tension stresses:
