Was ich jetzt mittels Hilfe doch noch herausgefunden hab:
1. In Explizit gehts scheinbar mitels general contact:
Other benefits of the general contact algorithm in Abaqus/Explicit include the following:
The general contact algorithm can enforce edge-to-edge contact for geometric feature edges, perimeter edges of structural elements, and edges defined by beam and truss elements,
unlike the contact pair algorithm.
2. In Standard gehts scheinbar auch über Tube-to-tube Contact Elements:
Tube-to-tube elements:
- model the finite-sliding interaction between two pipelines or tubes where one tube lies inside the other or between two tubes or rods that lie next to each other;
- are slide line contact elements, in the sense that they assume that the relative motion of the two tubes or pipes is predominantly along the line defined by the axis of one of the tubes (the relative rotations of the tube or pipe axis are assumed to be small);
- can be used with pipe, beam, or truss elements; and
- do not consider deformations of the tube or pipe cross-section.
The tube-to-tube contact elements can be used to model two specific classes of tube-to-tube contact problems: internal (tube within a tube) contact and external contact, where the two tubes are roughly parallel and contact each other along their outer surfaces.
It is not possible to use the surface-based contact approach for problems where two three-dimensional tubes contact each other.
Das werde ich mal bei Gelegenheit ausprobieren.
