     in the absence of automated and customized methods and tools, some of today’s existing methods for solving three-dimensional fracture problems require comprehensive finite element meshing, labor-intensive analysis and post-processing efforts. in this study, a tetrahedral enriched element method and related applications are presented that demonstrate employment of fully unstructured tetrahedral meshes for general mixed-mode three-dimensional fracture problems. as in the case of hexahedral enriched elements, the tetrahedral enriched elements also alleviate the needs of pre- and post-processing the finite element model, allowing direct computation of stress intensity factors in the solution phase. in addition, when tetrahedral enriched elements are used, the crack front region can also be meshed using unstructured elements allowing direct use of automatic free-meshing programs. the applications presented are plane-strain central crack problem, mode-i surface crack in a plate, inclined penny-shaped crack, edge-cracked bar under constant heat flux and lens-shaped crack embedded in a large elastic body. the results obtained are in good comparative agreement with those available in the literature. thus, it is concluded that the enriched tetrahedral elements can be applied efficiently and accurately on a general three-dimensional fracture problem allowing usage of fully unstructured finite element meshes.
