In the present study the slamming problem is simulated by numerical methods for investigating the hydroelastic effect during the slamming process. Slamming with two viewpoints of rigid and elastic structures (hydroelastic effect) had been modeled. Due to high impact speed of slamming, inertial and kinematic effects are quite evident in hydroelastic model. The results showed that considering hyd...
Maximum carboxylation rate (Vcmax) is a key parameter to characterize the forest carbon cycle process. Hence, monitoring Vcmax of different types hot research topic at home and abroad, hyperspectral remote sensing an important technique for inversion. Moso bamboo unique type with high sequestration capacity in subtropical regions, but lack data major limitation accurately modeling cycling proce...
Abstract In this study, non-hybrid and hybrid (Kevlar, carbon glass) fabric epoxy composite laminates were fabricated with different stacking sequences by hand lay-up followed hot-compression molding. Experimental tests conducted to investigate tensile, flexural, hardness characteristics. It was found that the sequence did not significantly affect tensile strength values of composites; however,...
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...
