Calculation of stresses initiated by electrical explosion of conductors in a composite thick-walled cylinder

In various fields of engineering, such structural elements are widely used that, from the point view their strength calculation, can be referred to thin shells (tanks, reservoirs, cylinders, etc.). When calculating thin-walled shells, a number hypotheses adopted simplify solution problem. The problem is most simply solved within framework momentless theory according which only force normal section (the membrane force) different zero, and all moments transverse forces equal zero. paper presents an analysis dynamic loading material carried out by method electric explosion conductors (EEC). A composite cylinder, thick-walled cylinder made polymethylmethacrylate with axial hole pressed into aluminum shell, was chosen as experimental sample. sample loaded applying voltage conductor in form copper wire placed inside opening equation state at obtained; calculated graphs dependence pressure air channel on expansion coefficient EEC products constructed. theoretical model describing change radial stresses arising process regard for boundary initial conditions built. accuracy built justified comparing obtained results data. circumferential stress, rupture shell directly occurs, estimated.
