metadata.value: The paper presents a dynamic loading analysis of a material carried out by the exploding
  wire method (EWM). A composite cylinder is chosen as an experimental sample. It is a
  thick-walled cylinder made of polymethyl methacrylate with an axial bore formed therein,
  pressed into an aluminium shell. The sample was loaded by applying an electric voltage
  to a conductor in the form of a copper wire placed inside the axial bore of the sample.
  An equation of state for an electric explosion of a conductor obtained. Dependence between
  the pressure in the air channel and the expansion coefficient of the EWM products
  demonstrated with comparison charts of the experimental and theoretical values. A theoretical
  model that describes the amplitude characteristic of the radial stresses arising during
  the loading is constructed, taking into account the boundary and initial conditions. The
  substantiation of the model accuracy is given by comparing the obtained results with experimental
  data. The estimation of the circumferential stress at which the aluminium shell
  breaks directly performed.
