SCIENTIFIC AND TECHNICAL SECTION

The effect of reinforcement schemes and angles on the stress-strain state and strength of single- and two-layer wound composite cylinders of finite length with symmetrical reinforcement of the layers under the internal explosion of a spherical explosive charge in the center of symmetry of cylinders in an air environment has been numerically investigated. The obtained results allow one to choose reinforcement schemes and angles which ensure the highest and lowest initial strength of cylinder according to the maximum stress and strain criteria and the generalized von Mises criterion, as well as circumferential rigidity.
