The Use of Pressure Pulses Arising from the Creation of Strong Pulsed Magnetic Fields for the Study of the Dynamic Strength of Materials

Abstract

Experiments on studying materials properties demand not only full information on the parameters of the acting loading pulse, but also the use of such loading conditions that allow us to carry out the analytical analysis of the deflected mode. It is obvious that the complexity and multifactority of the destruction process is aggravated in dynamic loading with occurrence of additional parameter, namely the shape and duration of a loading pulse. To study the destruction of faultless samples in dynamics the scabbing loading conditions are traditionally used. Scabbing loading allows carrying out pulse tensile pressure produced by a stretching wave, arising due to reflection of the compression wave from a free end face of the sample. In such situation for destruction, except for the characteristics of a material, the amplitude, the form, and duration of the pulse are responsible for the destruction.
