Face Load (Crack)
Add a Face Load subnode under a Crack node to describe a load acting on a crack face. In some cases, a Boundary Load can be used to the same effect. If, however, a J-integral is to be computed, and it encloses a loaded part of the crack face, then the load must be described using the Face Load node.
The Face Load node is only available with some COMSOL products (see https://www.comsol.com/products/specifications/).
Load
Enter the Crack face pressure, p. The pressure is applied to both faces of the crack.
See also J-Integral Theory in the Structural Mechanics Theory Chapter.
You can assign this load to a load group. See Load Cases in the Structural Mechanics Modeling chapter.
