- Abstract
- Results of experimental researches of strength for composite shells made from fiber windings to action of sidelong non-stationary loading are represented. Devices for generation of pressure pulses with a complex spatial-temporary profile and means of measurement of reaction parameters for researched objects on dynamic and pulse loadings are briefly described. Influence of pulse duration and the sizes for area of pressure application on character of destruction of the empty and filled shells is studied. It is shown, that on shell stage of deformation for criterion of destruction it is possible to accept achievement by the maximal county deformations of some limit level (about 2 %). The method of estimation for the maximal county deformation size by known characteristics of shell and parameters of loading is suggested.
