Measurement of the transmitted impulse from hemispherical charges
نویسندگان
چکیده
In the present study the impulse Ib transmitted by a hemispherical contact charge is calculated analytically and compared with experimental measurements. The impulse is measured experimentally with the use of a ballistic pendulum. The explosive charge is placed on a disk shaped striking mass. The mass is in contact with a nondeformable tubular structure placed on an instrumented base on a ballistic pendulum. The detonation of the explosive causes the impact of the striking mass on the tubular structure and the swing of the pendulum. Keywords— contact blast, ballistic pendulum, impulse

EXPERIMENTAL EVALUATION OF BLAST WAVE PARAMETERS IN UNDERWATER EXPLOSION OF HEXOGEN CHARGES
Behavior of blast wave in underwater explosion is of interest to metal forming community and ship designers. Underwater detonation is, also a potential hazard to the water intakes or a plant spent fuel pool. In this paper, some techniques for calculating free-field blast parameters such as pressure and impulse in underwater explosion and prediction of bubble pulsation parameters are presented a...
متن کاملParametric study of nonlinear buckling capacity of short cylinders with Hemispherical heads under hydrostatic pressure
This study investigates the buckling behavior of short cylindrical shells with hemi-spherical heads subjected to hydrostatic pressure. It is assumed that the length of the cylindrical part is smaller than or equal to its diameter while its material may be dif-ferent from that of hemispherical heads. Finite element analysis was used to seek out the effect of geometric parameters such as thicknes...
متن کاملSecrecy of Communications in Data Transmission by Impulses with Unknown Moments of Appearance and Disappearance
We carried out a comparative analysis of the algorithms for detecting a rectangular impulse against Gaussian white noise under either authorized or unauthorized access to the transmitted data. We presupposed that for data transmission the binary communication system is used and that the useful information in the data is whether the signal is present or absent. The case is that unauthorized acce...

The analysis of data derived by full-waveform laser scanning systems is of great interest. In this study, we estimate the impulse response of a laser scanning system capturing the waveform. Considering the impulse response of the system is important for precise waveform analysis. The characteristic of the system has to be mentioned to interpret the pulse properties in an accurate way. We determ...

Human Immunodeficiency Virus (HIV) weakens the immune system in confronting various diseases by attacking to CD4+T cells. In modeling HIV behavior, the number of CD4+T cells is considered as the output. But, continuous-time measurement of these cells is not possible in practice, and the measurement is only available at variable intervals that are several times bigger than sampling time. In this...
