Fig. 2. Load - time records resulting from the SSRT-FIP tests (a), (c), (e), (g) and the subsequent fracture tests in air (b), (d) and (f) of flat notched specimens P8, P3, P6 and P2..

Fig. 3. Fracture surfaces of the tested specimens: a) P8; b) P3; c) P6; d) P2..

3.2. Environmentally assisted cracking and final collapse processes Fig. 3 shows the macroscopic fracture surfaces of the four SSRT-FIP tested specimens. In the first three cases (Fig. 3a, Fig. 3b and Fig. 3c), heat tinting was used in order to discriminate the FIP assisted subcritical cracking
