Crack tip: A crack tip is a singular point where the crack starts to propagate. Abaqus allows users to define a crack tip using a node or an element. Crack front: The crack front is the boundary between the cracked and uncracked regions. Abaqus provides several methods for defining the crack front, including the use of a curve or a surface.
