Here are the summarized general rules (RG) of design, categorized by common topics. The competitive and innovative advantages are highlighted in bold, and their application is illustrated with Figures or Tables.

RG-TEFA-04. For fracture failure cases and constant build orientation, the method to be used to predict failure will depend essentially on the type of material: For ductile material, use the J integral method, and for brittle material, use the conventional linear elastic solid method.
