In order to characterize the fracture toughness of single edge notched tension (SENT) specimens, this paper describes the experimental determination of fracture mechanics parameters such as crack mouth opening displacement (CMOD) and crack type opening displacement (CTOD) on SENT specimen samples. Additive production techniques were used to make these specimens. This is an FDM (Fused Deposition Modeling) technique and the material used is polylactide amide (PLA, German RepRap Premium Filament). The experiment was performed on two models of test specimens that differed in geometry. The specimens differed in the length of the notche and crack, while the cross-sectional area of the specimens was equal. The experiment was performed at room temperature and relative humidity of 40%, a few days after production. Universal machine for testing the mechanical properties of materials (Shimadzu AGS-X 100kN) in the control of displacement at a speed of 0.5mm / min was used. Using the Aramis 2M syst...em, digital image correlation was used to obtain CMOD and CTOD (δ-5) values according to a standard procedure using a point-point distance command that measures the distance between points with an accuracy of one thousandth of a millimeter. The repeatability of the results indicates the same trend in the fracture of SENT specimens made by this technique of additive production and from this material as the results with low values of standard deviation.
