Abstract

In this article, we determined experimentally the response and made an estimate of the strength of fiberglass spherical shells,500 mm in diameter of two types of winding under radial-symmetric internal explosive loading. The advantage of shells with a more uniform thickness (15–20mm) of the load-carrying fiberglass layer is shown. On explosion of a charge involving an energy equivalent to1.4 kg ofTNT, this layer has an approximately twofold strength factor. It is established that the change from uniaxial (cylindrical shells) to biaxial strain in spherical shells does not change the magnitude of total strain at failure.
