Bonded |
Available for all types of studies that require meshing. The program bonds the Set 1 and Set 2 entities. The entities may be touching or be within a small distance from each other. If there is a gap between the entities, the program issues a warning message that the physical gap between the bonded entities may produce incorrect results. The user may still insist in defining a bonded contact set. The software then enforces a bonding set regardless of the existing tolerance between the selected entities.
For drop test studies, you can only bond touching faces. Compatible bonding is enforced via component or global contact. Local bonded contact sets with incompatible bonding are not supported.
Bonded Contact
For a study with mixed mesh (used automatically by program), you can bond Set 1 entities (vertices, edges, faces, beam joints, and beams) to Set 2 faces. Vertices, edges, and faces can belong to shells or solids. The behavior of the bond depends on whether the source entity belongs to a solid or a shell. If the source entity belongs to a shell or beam, the bond acts like a rigid connection where the original angle between the shell or beam and the solid is maintained during deformation. If the source entity belongs to a solid, the bond acts like a hinge, where the original angle between the shell and the solid is not necessarily maintained.
When bonding a shell edge to a solid or shell target face, the software rigidly bonds each node of the edge to the nearest element's face on the target. The rigidity of the connection depends on the element size near the interface. To improve accuracy, the element size on the target face should be equal to the thickness of the shell if no weld is used. If a weld is used, the element size on the target face should be equal to the weld size.
