Abstract (EN): This study reviews some approaches employed to evaluate the Stress Intensity Factor (SIF) in structural components with plane cracks. Several experimental and computational methodologies have been practiced to assess the fracture response under different material behaviors. Amongst all, Digital Image Correlation (DIC) and Thermography methods (Thermoelastic Stress Analysis-TSA) were used to monitor the fracture behavior contributing to characterize the SIFs. The applied experimental methods are contactless full field optical measuring system in which they provide deformation fields and the stress variation. Hence, it would be valuable to appraise the performance of numerical formulations; therefore, the Finite Element Analysis (FEA) was considered for validation purpose. Theoretically, it aims at expansion an analytical solution to SIF determination, following the compliance functions together with the stress dead-zone notation. Overall, this review manuscript presents examples focusing on the fracture and SIF characterization resorting to the different material behaviors in accordance with the mentioned techniques.
