METHOD FOR REVEAL OF CHANGE OF STRUCTURAL STATE OF PLASTIC MATERIALS IN PROCESS OF SUDDEN CHANGES IN MODE OF LOADING

摘要

Method for reveal of change of structural state of plastic materials in process of sudden changes in mode of loading relates to area of material testing. The method is in fact that sample of material under investigation is tested at given variable mode of power loading. In process of testing on that sample, synchronously with general information of material of sample, one fixes cross deformation, change of electric properties, with determination of deformation of detachment. The procedure of testing described makes it possible, by simultaneous sudden change of electric properties and detachment deformation, to make with high probability conclusions on chamber of structural state of plastic materials at given level of plastic deformation in process of sudden changes under effect of different temperature-force conditions of loading.
