چکیده
Abstract During the PTFE/Al reactive shaped charge jet formation, burst wave generated by explosion of explosive is sufficient to achieve ignition conditions materials (RMS). As a result, RMS will react, resulting in an energy loss from jet. In order research forming features and during liner with diameter 74 mm was prepared X-ray pulses photography experiment performed on formation. And parameters Johnson-Cook constitutive model were obtained through quasi-static experiments Hopkinson pressure bar experiments. The formation simulated, AUTODYN secondary development technology used. results show that can intuitively reaction active material less cohesive, its thicker, morphology divergent. reacted inner layer collided. Therefore, most chemical reactions occur inside

The capability of the generalized interpolation material point (GIMP) method in simulation of penetration events is investigated. A series of experiments was performed wherein a shaped charge jet penetrates into a stack of aluminum plates. Electronic switches were used to measure the penetration time history. Flash x-ray techniques were used to measure the density, length, radius and velocity o...

A spectrophotometric study concerning the interaction between Trimethoprim (TMP) ,Sulfamethoxazole (SFMx), as n-donor and 2,3-dichloro-5,6- dicyano-P-benzoquinine (DDQ) and chloranilic acid (CA) as π-acceptor were been performed at 25°C. The results of interaction of CA and DDQwith TMP indicate the formation of a 1:1, 1:2, charge transfer complexes through non equilibrium reactions. In the case...
