Abstract
The invention relates to area of material testing, in particular to methods for prediction of limit damage of plastic materials at complicated mode of loading (static elongation – dynamical overload – static elongation) by results of tests of small samples. Method for prediction of limit damage of deformed plastic material includes testing of smooth small samples made of material in initial condition with any operating time under conditions of equilibrated static elongation with determination of coefficient of transverse deformation at all stages of deformation by which one makes conclusion on level of damage (loosening) of material in process of deformation ant its limiting value. At given stage of deformation at static elongation one additionally tests series of small samples made of specific material at different increasing values of intensity of dynamic pulse, one determines maximal value of dynamical pulse at which the sample practically at once is separated into two parts and respective limiting minimal value of level of damage of material at dynamic overload, and on effect of intermediate values of intensity of dynamical pulses on current limit values of level of damage of material at following static elongation one makes conclusion from given mathematical relation. Technical result is in increase of reliability of prediction of limit values of level of plastic material damage at complicated mode of loading (static elongation – dynamical overload – static elongation) under effect of dynamical pulses with given intensity at any stage of deformation.
