The paper presents the results of experimental studies of impulse-shock loading on alloys with shape-memory effect, polymers, and metals. During the experiment, qualitative characteristics of materials are obtained due to use of qualimetry methods. Five dynamical characteristics of loaded alloys, polymers, and metals are selected; the results of their estimations are plotted on the ‘web of quality’ cyclograms. In addition, for the investigated materials, quality-grading tables are composed on basis of the desirability function using. As practically proved, the nomograms’ data on definition of the desirability index can be used to evaluate the quality of samples from polymethyl methacrylate at pulsed loading by such parameters as load amplitude, crack propagation length, and energy. As a result of the research, it is found that the quality of the sample can be determined by two ways: by complex index or by individual unit parameters. The dependence of the length of the sprouted crack on the average filler size for different materials of samples is established. As proved, the steel 30ХН4М has optimal characteristics in terms of resistance to impact load.
Key words: alloys, polymers, metals, high-speed loading, methods of qualimetry.
