“…That is why, materials with good specific strength, stiffness, resistance to extreme environmental effects are required which is only possible while using these high-performance composites [5][6][7]. For instance, bird strikes in aircraft and blast loading in the submarine hull are few of the examples [8,9], which led to the essential characterizing of composite materials under high strain dynamic impact.…”

Vast research has been going on to improve the mechanical performance of carbon fiber reinforced polymers composite (CFRP) when subjected to quasi-static loading but investigation and modification of their dynamic behavior are still underdeveloped. This paper presents an experimental investigation on the effect of randomly dispersed graphene nanoplatelets (GNPs) on the mechanical properties of CFRP composites under dynamic loading. Four different mass fractions of GNPs, 0%, 0.5%, 1%, and 2%, were considered in the experiments. Specimens were tested experimentally using the split Hopkinson pressure bar device (SHPB) to examine their dynamic response and damage behavior at high strain rates. During the dynamic compression tests, a high-speed camera was used to monitor and record the damage kinetics. The experimental characterization showed that the integration of GNPs has greatly influenced the dynamic response and damage mechanism of the CFRP. Composite doped with 1% GNPs demonstrates the optimum enhancement of the mechanical properties of the composite specimens and shows an increase of the dynamic characteristics and fracture resistance.

“…The sudden release of energy associated with the explosion of a high explosive leads to generation of a shock wave and formation of a superheated, highly compressed gas bubble in the surrounding water [2]. The underwater targets are defeated by shock or bubble or combined effect, unlike in air blast [3]. Type and extent of damage depends on whether the explosion has taken place in contact with the target or at proximity.…”

“…Many studies of close proximity UNDEX have been primarily concerned with shock wave interactions with a target and damage (e.g. [12,20,25,[28][29][30][31]34]). Other studies have examined the effect of the target on the dynamics of the gas bubble (e.g.…”

The study describes recent simulation results for underwater explosions in close-proximity to rigid targets. Simulations are performed using Chinook, an Eulerian computational fluid dynamics (CFD) code. Predicted target loadings are compared with measurements taken from a series of experiments conducted under an international collaboration between Canada, The Netherlands, and Sweden. The simulations of the rigid target tests focused on the modelling of gas bubble collapse and water jetting behaviour. Both two-dimensional and three-dimensional simulations were performed. It was found that the two-dimensional analyses produced good bubble periods and reasonable impulse loading compared to experimental data. The time of arrival of the bubble collapse and water jetting were found to be very mesh dependent and refining the mesh did not always produce better results. The two-dimensional approach provides a good initial understanding of the problem for a reasonable computational effort. The three-dimensional simulations were found to produce improved impulse predictions. The numerical gas bubble radii time histories are also compared to empirical time histories.
