Computational Investigation of the Effect of Reinforcement Schemes and Angles on the Stress-Strain State and Strength of Composite Cylinders Under Axisymmetric Internal Explosion. Part 3. Results of Calculations for Two-Layer Cylinders with Orthogonal and Combined Reinforcement of the Layers

The effect of reinforcement patterns and angles on the stress-strain state and strength of two-layer wound composite cylinders of finite length with orthogonal reinforcement and two types of combined reinforcement of the layers under axisymmetric internal explosion has been numerically investigated. Using the data presented in Part 2, a comparative analysis of the effect of winding angles on strength for five different reinforcement patterns has been performed according to three failure criteria for an anisotropic material. The obtained results allow one to choose reinforcement patterns and angles, which ensure the highest and lowest initial strengths of the cylinder, according to the maximum stress and strain criteria and the generalized von Mises criterion, as well as circumferential stiffness.
