Samenvatting

Novelly-designed thin-wall TRC shells are tested simulating service loads. The study tracks the main damage modes (cracking/interfacial delamination) using the Acoustic emission (AE) wave parameter trends and based on it, a novel multi-sensing and multi-input (experiments/simulations) methodology is built. It is shown that stronger shell curvature influences the stress field and the damage mode towards shear, something monitored by early AE even before visible cracks occur, while boundary conditions and the textiles volume content also have an effect on the TRC shell damage progress. The AE inspection efficacy is critically assessed considering the detrimental wave attenuation effect.
