Anisotropic elastic capability (TB,ANEL or TB,ELAS,,,,AELS/AELF) is available with current-technology plane and solid elements. The element coordinate system is used for defining anisotropic material input. Unless otherwise changed, the element coordinate system orientation is the default orientation for that element type. The orientation may be changed for area and volume elements by making it parallel to a previously defined local system (ESYS). Check this - Understanding the Element Coordinate System.
