 12 PLA plates with W=60 mm, a=30 mm (a/W=0.50), with 2 different thicknesses (5 mm and 10 mm) and 2 different notch radii (0.9 mm or 1.3 mm).  15 PLA plates with W=120 mm, a=30 mm (a/W=0.25), with 2 different thicknesses (5 mm, 10 mm, and 20 mm) and 2 different notch radii (0.9 mm or 1.3 mm).  12 PLA-Gr plates with W=60 mm, a=30 mm (a/W=0.50), with 2 different thicknesses (5 mm and 10 mm) and 2 different notch radii (0.9 mm or 1.3 mm).  15 PLA-Gr plates with W=120 mm, a=30 mm (a/W=0.25), with 2 different thicknesses (5 mm, 10 mm, and 20 mm) and 2 different notch radii (0.9 mm or 1.3 mm).

Figure 2: Geometry of the tested plates. ρ : notch radius; a: crack length; W: width; α : notch opening angle; L: length.
