Experimental study of the influence of strain-stress state on the jerky flow in metals and alloys

This work is concerned with improvement of experimental methods for studying the influence of the stress-strain state on the spatial time inhomogeneity die to the jerky flow of Al-Mg alloys and carbon steels. The implementation of a complex stress state is based on the use of specimens with special complicated geometry. Mechanical tests were carried out on uniaxial tension of plates with a rigid rim, in the working part of which biaxial tension...
