The flight deck of an aircraft carrier is subjected to various loads. In addition, the operation fixed-wing presents unique structural requirements for deck. This paper, therefore, compares behaviour a which was designed following guidelines three classification societies: Lloyd’s Register (LR), Det Norske Veritas Germanischer Lloyd (DNV), and Registro Italiano Navale (RINA). loading scenarios ...

All the existing loading protocols have been developed independently of the value of the behaviour factor q that the structure has been designed for. Conservatively, a single loading protocol is adopted, for all q values, based on the structural system with the most onerous cumulative seismic demands. However, analyses conducted by the authors, show that imposed cumulative seismic demands decre...

nowadays, consumers demand safe and minimally processed foodstuffs without additives and with extended shelf life. as high-pressure processing is used increasingly for the treatment of packed products, different packagings has been investigated with respect to their structural behaviour and stability under high-pressure processing. various defects may ocuure due to high pressure processing such...

This paper numerically discusses how the performance of a NACA marine propeller is affected by the number of blades, which is one of the most crucial geometrical parameters determining the performance of a propeller. Results are presented in terms of the hydrodynamic and structural parameters. The results show that changing the number of blades changes the hydrodynamic efficiency, torque, thrus...

Semi-buried structures are most commonly used at first line of defense along the border between two countries. This demands investigation of their dynamic behaviour under blast loading. Herein, a semi-buried structure with foam sandwiched walls and buttresses to reduce the effect of blast is analysed. The effect of provision of different configurations of buttresses and foam core between two la...
