Abstract:

In this study, the dynamic behavior of a hemispherical composite shell manufactured from fiberglass and epoxy under air blast load has been analysed experimentally and numerically. A blast load test structure and a hemispherical composite shell has been designed and built. Static tests has been conducted for material calibration and air blast load tests have been done under different pressure and distances. The equations for composite and shell structures were derived. The theoretical part of the study also contains the finite element analysis of the composite shell structure via ANSYS. The frequency response of the shell, computed by the finite element method, for the air blast load shows good agreement qualitatively with experimental results.
