Fig.9 shows a comparison of the evolution of the damage for different loads by analytical<br />

means using Eq. (4), as proposed by Mao and Mahadevan (2002) and the experimental<br />

approaches. Fig.10 shows an image of the thermal distribution on the surface of the examined<br />

specimens provided by an infrared camera. It shows that the hot zone is localized at the<br />

centre of the specimens. The correlation between the increase of temperature and the damage<br />

evolution in the composites was done by using this thermography and experimental data.<br />

Fig.11a, Fig.11b, and Fig.11c show a comparison between the change of temperature and the<br />

damage at different loadings.<br />
