On the stability of the nonlinear-elastic cylinder stretching
UDC
539.3Abstract
Applying Blatz and Ко model of compressible nonlinear-elastic material some characteristic features of the cylinder stretching under extra-large deformations were studied. It provides a method to determine the area of constitutive parameters, which presuppose existence of the falling section within the tensile diagram. The analytical study of the stability of solutions corresponding to the falling section was carried out within the framework of the bifurcational approach.
