ANALYSIS OF INFLAMMABLE STATE OF PURCHASE AT THE WALKING
Bubnovska Irina – Assistant Professor of the Department of “Electrical Engineering, Electrical Engineering
and Electromechanics” of the Vinnytsia National Agrarian University (3, Sunny St, Vinnytsia, 21008,
Ukraine, e-mail: biana25100@gmail.com).
ANALYSIS OF INFLAMMABLE STATE OF PURCHASE
AT THE WALKING
On the basis of the equilibrium equation, the plasticity conditions in the zones of plane strain, the
equation of the connection of the components of the stress tensor and the strain rate tensor, an expression
was obtained for determining the stress state parameter, which makes it possible to estimate the deformity
of the workpiece material during rolling.
Key words: rolling, index stress state, strain rate, stress tensor, hydrostatic stress.
