In the present study, progressive failure analysis of carbon fiber reinforced polymer (CFRP) panel is carried out under flexural loading. The flexural properties of CFRP panels are characterized using four-point bend fixture and the same fixture is used to perform failure analysis of CFRP panels have different open cut-outs in form of multiple holes. The interaction between multiple holes with different configuration like two holes in longitudinal direction (2HL), transverse direction (2HT) or in diagonal direction (2HD) are carefully studied. Experiments are carried out using digital image correlation (DIC) to measure through-the-thickness strain distribution in all configurations. Failure propagation, final failure load and load-displacement profiles are analysed and compared with each other. Later, a finite element based progressive damage modelling (PDM) is implemented to study the damage initiation and propagation in CFRP panels.
