2. Methods and materials 2.1. Modeling method

The modeling method works by simplifying the built configuration using a homogenous material. Therefore, an equivalent model was used to model the mechanical behavior, including the crack propagation and the stress intensity factor. The developed work is presented in Fig. 1, which be detailed next.

Fig. 1. Definition of the numerical model.

2.2. Model creation

The procedure starts by creating a 3D model of specimens according to ISO 527 type 2 or ASTM D638 for the characterization, and a simple edge notched tension SENT for crack propagation study; its geometry and dimensions are shown in Fig. 2.
