In the last years, new connectors of steel-concrete composite flooring systems have been developed and investigated to enhance circularity standardisation building components. Recent studies showed that timber can be used as an alternative concrete slab in hybrid structures. However, knowledge steel-timber is still very limited. This contribution presents numerical investigations steel-LVL beam...

This paper presents the simulation results of acoustic field around an underwater supercavitation vehicle under various operating conditions and analyzes cavitation phenomenon hydrodynamic noise spectrum. Regarding ventilated phenomenon, shows that low speed can reduce threshold supercavitation, high background pressure enhance stability structure. As for noise, firstly, reveal when occurs, spe...
