- The objective has been stated to investigate the capability of materials and structures to with stand to impact loading. Computerized research complex has been developed and manufactured to carry out experiments on impact interaction of specimen with an accelerated to a certain velocity piercer. The complex includes ,,GANCHEN"-type thermogas ballistic gun for piercer accelerating, piercer velocimeter, ballistic pendulum for measurement of integral energy datum of piercer-specimen interaction, and ,,ODD" device for measurement of residual deformation of the specimen. The experiment progress control, gaging equipment sensor signal processing and obtained information data storage are accomplished at researches. The elaborated system and research techniques permit carrying out a series of comparative check tests of specimens of different metal-composite constructions. Measurement of damages of a multilayer composite surface, the principal scheme of the thermal gas ballistic laboratory installation, basic and structural schemes of optical detector of deformations ODD-C, dependence of the optical gauge displacement, a screenshot of the developed software for the ,,ODD" device operation, the scheme of the contactless surface deformation damages scanning method, calculation algorithm of the scanned surface coordinates, appearance of the material samples after punching with a spherical piercer and computer representation of measurements of damaged zones, results of research of metal-plastic composites, increase of ability of samples to absorb the energy of the sphere, discrete character of deformation distribution are presented in the paper.
