Application of the electromagnetic model for diagnosing shock–wave processes in metals

To verify the electromagnetic model of shock compression of a conductor in an electromagnetic field, shock–wave experiments with Constantan are performed. The test results show that the electromagnetic model gives a qualitatively correct description of the phenomenon. Some disagreement between the numerical and experimental data may be caused by factors ignored in the model (a finite thickness of the shock–wave front and the nonuniformity of the shock wave and electromagnetic field in the measurement cell). Electric conductivity of Constantan is determined experimentally under conditions of single shock compression. These studies justify the electromagnetic model of shock compression of metal in a magnetic field and form the basis for development of new techniques for dynamic experiments.
