**r7.02.20** Computation of T-stress by extrapolation of displacement field
===========================================================================

**Abstract:**

The computation of T-stress is implemented for linear, homogeneous and elastic-isotropic materials with plane crack mesh (FEM only). The accuracy of T-stress results obtained by extrapolation of the displacement fieldmethod is clearly improved if the meshing elements are quadratic. It is also highly recommended to use "Barsoum" type elements in the crack tip (elements where the mid-side nodes are located at the quarter of edges).
