“…The liner made of solid Al with the angle of 55°/60° at the top produced a hole 1.8-1.9 times larger in volume, as a result of the explosion of a charge with a diameter of 26 mm. The mass of the explosive material (RDX or Okfol) was 10 g [6][7][8]. The pressure of the charge's compression was (8.1-10.8)•10 8 Pa.…”

“…The internal energy of shock compression is equal to the area under the curve p(V). In the range of pressure and porosity used the behavior of materials, including composites, is described by the normal process of adiabatic shock [6,7,9]. The results of calculations for copper, nickel and aluminum are given in Table 1.…”

“…Experiments with shaped charges were carried out according to a well-known methodology [6]. RDX (hexogen) or Okfol (octogen/inert material 96.5/3.5) charge, covered with a cap was installed directly on the target, which the top part was constructed as follows: made of steel plate (St3) (δ = 10 mm) and the base was made of Al-Mn alloy in the form of a pack of plates.…”

“…The influence of the shape of the liners (porous and solid) on the degree of target damage has been determined experimentally using liners made of powdered metals such as Cu, W, Pb, Ni, Al as well as solid liners made of Al and Cu in conditions of shock-wave loads and jets flows on brittle and ductile materials [6][7][8][9]. According to [10] the influence of the pore air and alloying additives (WC, C,…”

Purpose. To study the laws of deformation and destruction of brittle and ductile rocks and concretes under explosion of industrial shaped charges. Methods.In experiments, the following methods of investigation were used: method of contact sensors for determination of jet velocity; determination of the ultrasonic wave velocity in the concrete samples; methods of optical and electronic microscopy; X-ray phase analysis; measuring and visual analysis of the dimensions and nature of deformation and destruction zones.Findings. The work describes the experimental data on the destruction of barriers made of concrete, granite, steel ST 3, AMC-n alloy, and zinc by the explosions of shaped charges of serial production with porous liners. Calculation formulas for estimating the radius of a destruction zone of geomaterials and rocks in case of a semi-infinite barrier are suggested. The calculation method is based on the estimation of energy impact on the rock by jet penetration velocity into the barrier. Jet velocities are determined experimentally and by engineering methods. The reasons for deviations in the hole shape and deflection of the destruction zone from the symmetry axis were determined.Originality. The modes of penetration of shaped jets into rocks of different porosity, the size of the fracture zone around the hole and the causes and mechanisms of the deviations of the hole shape from the symmetric one are established. Practical implications.The results of the research will be used to design blasting-and-perforation operations in geotechnological wells and can be used to design initiating devices for borehole charges.
