Comment [HRM1]: Revise? In conjuction and continued following that was the research on anisotropic materials, learning basic FORTRAN programming, and programming a 2-D isotropic User Element (UEL) in Abqaqus to implement the Complex Taylor Series Method (CTSE) to the built-in Abaqus elements. Upon completing programming of a 3-D Isotropic element implementing CTSE will be continued work throughout the semester. ANISOTROPIC MATERIALS Anisotropic Materials Anisotropic materials are materials whose properties are directionally dependent. Unlike isotropic materials that have material properties identical in all directions, anisotropic material’s properties such as Young’s Modulus, change with direction along the object. Common examples of anisotropic materials are wood and composites. Implications Directionally dependent physical properties of anisotropic materials are significant due to the affects it has on how the material behaves. For example, in the case of fracture mechanics, the way the microstructure of the material is oriented will affect t
