11.4 Supplementary edge-to-surface formulation for general contact

Product: Abaqus/Standard  

Benefits: The edge-to-surface formulation often provides better resolution of contact involving feature edges.

Description: A supplementary edge-to-surface formulation has been added for general contact in Abaqus/Standard. The general contact capability relies on the surface-to-surface formulation to resolve most contact involving surfaces with nearly opposing normal directions. General contact can now also use the edge-to-surface contact formulation to more accurately resolve contact involving feature edges where an oblique angle exists between surface normals in the active contact region, such as in the snap-fit example shown in Figure 11–2. This capability is limited to feature edges of solid, three-dimensional bodies.
