Figure 2 : Manufacturing direction and orientation of the deposition filaments. The adopted symbols as well as the meaning of the effective stress determined according to definitions (3) and (4) are explained in Fig. 1. As to the different formalisations of the TCD, it is worth mentioning here that this powerful theory can be applied also in the form of the Area Method (AM) [1, 12] as well as of the Volume Method (VM) [1, 13].
