A High-Velocity Impact Simulation using SPH-Projection Method
In this paper, a new smoothed particle hydrodynamics (SPH) algorithm for simulation of elastic-plastic deformation of solids was proposed. The key point was that materials under highvelocity impact (HVI) behave like fluids. This led to propose a method which was similar to the socalled SPH-projection method, in which the momentum equations are solved as the governing equations. The method consi...
متن کاملDamage Assessment in Glass Fiber-Epoxy Matrix Composite under High Velocity Impact of Ice
This study investigated the influence of nanoclay on the impact damage resistance of glass fiber-epoxy composites under high velocity ice impact loading. Addition of 0.5 wt. % nanoclay into epoxy was shown to improve damage resistance compared to composite plates having no nanoclay platelet. The glass fiber-epoxy composites containing nanoclay brought about substantial improvement in ice impact...
متن کاملHigh-velocity impact properties of multi-walled carbon nanotubes/E-glass fiber/epoxy anisogrid composite panels
This work reports the high-velocity impact response of multiscale anisogrid composite (AGC) panels. The aim of the present study is to evaluate the influence of surface-modified multi-walled carbon nanotubes (S-MWCNTs) at different S-MWCNTs contents (0-0.5 wt.% at an interval of 0.1 wt.%) on the high-velocity impact responses of E-glass/epoxy AGC. Surface modification of MWCNTs is confirmed by ...
متن کاملFragmentation of ice by low velocity impact
Low velocity impact experiments (0.14 to l km/ s) carried out in polycrystalline water ice targets at 257 and 81 K resulted in interactions which can be assigned to four fragmentation classes, cratering, erosion, disruption, and total fragmentation. Specific kinetic energies for the transitions between these classes range from l x 105 to 7 x 105 ergs/g for 81 K ice and from 3 x 105 to 2 x 106 e...
متن کاملBone Fractures Produced by High Velocity Impacts '
The effects of high velocity impact to the distal end of 122 human femurs were studied using one-quarter inch steel spheres as projectiles, with impact velocities from 500 to 1700 feet per second. In the lower velocity range, a "drill hole" fracture was produced with low energy expenditure, and the diameter of this type of fracture was increased as a function of increasing velocity. At the high...
