Advanced composites have a brittle nature making them highly susceptible to failure and propagation under impact loading conditions. Appropriate modeling techniques accurately simulate these conditions are required. This study presents examines coupled thermo-mechanical technique its associated numerical simulations for analyzing carbon fiber-reinforced composite panels subjected high-velocity ...

Effects of some important parameters like impactor effects, plug geometry and initiation points on bonding aluminum tubes to aluminum plugs were studied. The impact velocity and dynamic angle between tube and plug should be precisely managed to achieve an optimum bonding condition. A new explosive bonding technique with the use of two material impactors was proposed. Results are especially suit...

When penetrated by a high-velocity projectile, fluid-filled container can be severely damaged and ruptured due to the intense impact loading from Hydrodynamic Ram (HRAM), which causes primary shock wave, then subsequent phase when cavity evolves in fluid. In design of fuel tanks for aircraft, other transport vehicles, HRAM pressure is major concern reliability structure. this paper, experiments...

OBJECTIVE To examine the effect of trauma velocity on the pattern of Le Fort I facial fractures. METHOD A retrospective medical record review was conducted on a consecutive cohort of craniofacial traumas surgically treated by a single surgeon between 2007 and 2011 (n=150). Of these cases, 39 Le Fort fractures were identified. Patient demographic information, method of trauma and velocity of i...
