Zachowanie się stopu aluminium PA4 podczas próby dociążania

The experimental results of load modulus measurement in the course of additional torsion were presented in the paper. The time agent was regarded. The experimental results were compared to theoretical ones which were obtained on the ground of the slip theory. It is proved that value of plastic strain in the course of load depends on the time which elapses between the moment of applying tensile stress and the moment of applying shear stress.
