Abstract
The invention relates to material testing. Method for weakening plastic materials in process of deformation is I fact that one in sequence statically elongates set of same samples of material under investigation to given level of deformation that is smaller than level of deformation that corresponds to strength limit of material. After that in sequence each of set of sampled continuously undergoes sudden changes in mode of loading by same complicated law in several steps. At first step one suddenly increases rate of deformation. At second step it is suddenly decreased. At third step one again suddenly increases it. On level of weakening of plastic material in process of deformation one makes conclusion by difference of resistance of material to deforming at static load at which sudden changes in load mode begin, and maximal level of decrease of resistance of plastic material to deformation at given complicated mode of loading. Given complicated mode of loading can be repeated many times with increasing average rate of deformation. The method makes it possible to control the process of decrease of strength properties of plastic materials at “classic” stage of strengthening of plastic material obtained at “pure” static elongation. The invention makes it possible to realize effectively controlled process of weakening of plastic materials at given stage of deformation.
