| Abstract |
We present the results of experimental studies of the strength of composite shells of cotton winding under the action of a lateral nonstationary load. We briefly describe devices generating pressure pulses of complicated space-time profile and the tools for measuring the parameters of the original object response to dynamic and pulse loadings. We study the influence of the action duration and the pressure application domain dimensions on the character of failure of empty and filled shells. We show that, at the shell stage of deformation, for the failure criterion one can take the moment at which the maximal circular strains attain some limit level (of the order of 2%). We propose some relations for estimating the maximal circular strain in terms of the shell characteristics and the load parameters. |
