Fig. 3. Representative load-displacement curves obtained from three-point bending tests.

Finite element analysis was implemented to calculate the critical values of J-integral (i.e., J c ) corresponding to the maximum loads obtained from the fracture experiments. To this end, a 2D plane strain model consisting of quadratic quadrilateral elements was created for each SCB sample. The mesh pattern and von-Mises stress distribution under the fracture load of 2715 N are depicted in Fig. 4 (for the SCB specimen with a nozzle diameter of 0.4 mm and raster angle of 0/90 o ).
