With dramatic increase in 3D printing applications industry, sandwich panels with printed cores have gained a lot of attention recently. In harmony global movement towards sustainability and low-carbon emission industries, easy-to-repair cost-effective would be very attractive structures. this regard, implementing separated cells for constructing lattice structures instead using back-to-back ma...

Nowadays, the floating production storage and offload system (FPSO) is one of most common platform types for offshore oil production. The traditional arrangement stiffened panels creates obstacles automated cleaning inspections by remote devices. This paper summarizes results an initial study design construction FPSO hulls with SPS in order to overcome this problem. main goal have walls bottom ...

Abstract A theoretical energy-based model to capture the ballistic response of sandwich structures made composite material peels and a crushable foam core was developed. The based on wave propagation theory it split in six stages with their corresponding energy-absorption mechanisms. division physical interpretation perforation process involving reasonable hypotheses simplifications. analysed a...
