This work presents the difference in the values of fracture mechanics parameters obtained by
testing of cylindrical specimens with a sharp notch, cut on the tip of a wider groove. The
samples were obtained using two different additive manufacturing techniques. The first type
of samples was obtained by the FDM (Fused Deposition Modeling) method, on the German
REPRAP X400 device with an average accuracy of 0.25 mm. The second type of samples was
made using the SLS (Selective Laser Sintering) method on the EOS Formiga P100 device with
a production precision of 0.08 mm. Regardless of the difference in manufacturing techniques,
the direction and orientation of the samples was identical. The samples were prepared so that
during loading the fibers are loaded in tension, i.e. axially. Different lengths of the sharp
notches were fabricated axially on the samples. The values of fracture mechanics parameters
such as CMOD (Crack Mouth Opening Displacement) and CTOD-5 (Crack Tip Opening
...
Displacement obtained using the -5 technique) were obtained using the digital image
correlation method. The obtained parameters, except for mutual correlation, were also used
for the verification of numerical results. In the future work, a procedure for determination of
energy-based fracture mechanics parameters will be developed for this sample geometry.
