Test Case
A rectangular plate with a center crack is subjected to an end tensile load 
. Symmetry boundary conditions are considered and T-Stress is determined using
Pre-Meshed Crack.

Analysis Assumptions and Modeling Notes
The problem is solved using 2-D solid elements with plane-strain behavior. A one-quarter plate is modeled and symmetric boundary conditions are considered. The crack tip nodes and the number of paths surrounding the crack tip nodes are defined using Pre-Meshed Crack. The plate is subjected to a tensile stress and the T-Stress is computed for the crack tip nodes. The crack front and the path surrounding the crack front are defined using Pre-Meshed Crack.
