The research is motivated by the need to develop advanced design methodologies for shell structures. For that purpose, strain gauges are utilized to monitor strain concentrations near the cracks, and finite element simulations are carried out to predict the corresponding stress intensity factor distributions. A good agreement between numerical simulations and experimental data is found. This confirms that virtual simulations/calculations provide a reliable approach to evaluating mechanical behaviour of pressurized cylindrical shells with crack defects. %G English %L hal-01944415 %U https://ensta-bretagne.hal.science/hal-01944415 %~ UNIV-BREST %~ INSTITUT-TELECOM %~ ENSTA-BRETAGNE %~ EM-DOUAI %~ ENSTA-BRETAGNE-LBMS %~ ENIB %~ UNIV-LORRAINE %~ INSTITUTS-TELECOM %~ ENSTA-BRETAGNE-MECA %~ IMT-NORD-EUROPE
