Abstract

Provided is a stress blank angle eliminating device and method for a dynamic true triaxial electromagnetic Hopkinson bar. Objectives of eliminating influence of a stress blank angle in a sample in a test and preventing permanent deformation caused by mutual collision between the Hopkinson bars are achieved. The adjustable test device for eliminating the stress blank angle eliminates influence of the stress blank angle generated by the sample in a triaxial six-direction dynamic impact test process, and is convenient for obtaining real dynamic failure parameters of the sample.
