- Abstract
- A set of gasdynamic devices for generation of side non-stationary loadings of various physical nature was described. Two new explosive devices for formation of low-pulse loadings of microsecond duration were offered. Methods of reaction parameters measurement of thin-walled composite constructions to action of dynamic and pulse loads were considered. The new method for registration of development of a non-stationary constructions displacement at the shell stage of deformation was offered. Results of shock and wave tests of carbon- and organo-filled plastics were given. It was received that use of wire or foil sensors for measurement of deformations yield close results when the shell stage of deformation of fiberglass thin-walled constructions is investigated.
