    Supposing an one-demensional cylindrical symmetry ( for motion of cylinders driven by detonation waves at tangential incidence), a semi-empirical equation is suggested for the calculation of the fragment velocity, in which the coefficients were determined from 47 experimental datums for 30 kinds of explosives. It is found to be applicable to every variety of explosive fills, density and charge to metal ratio. A good agreement exists between experimented and calculated values. Confidence interval equals 0.0012±...

    Supposing an one-demensional cylindrical symmetry ( for motion of cylinders driven by detonation waves at tangential incidence), a semi-empirical equation is suggested for the calculation of the fragment velocity, in which the coefficients were determined from 47 experimental datums for 30 kinds of explosives. It is found to be applicable to every variety of explosive fills, density and charge to metal ratio. A good agreement exists between experimented and calculated values. Confidence interval equals 0.0012± 0.0201 mm/μs for a degree of confidence 0.9.In similar manner, supposing one-dimensional plane geometry (for motion of plane driven by detonation waves at tangential incidence), a semi-empirical equation for calculating the fragment velocity is obtained, in which the coefficients were determined from 92 experimental data for 4 kinds of explosives There exists a good agreement between experimental and calculated values. Confidence interval equals - 0.006 ± 0.0143mm/μs for a degree of confidence 0.9.Gurney approach is discussed on the basis of one-demensional unsteady flow solut ion.

    Development of deformation and rupture for a cylinder shell under high-pressure explosion loading is very important in dealing with the direct accelerating and kill effect of the shell. The paper assumes the shell material as rigid and perfect plastic. The stress field, deformation speed, breaking radius and fragment velocity are approached. Comparison with experimental data has been made for 50 kinds of copper shell and Ⅱ kinds of steel shell filled with various explosives. All the results are in good agreement with the data. The relative deviations are 3% or so. The new model is suitable for engineering calculations.
