“…Thus, experiments with cylindrical fiberglass shells subjected to internal explosive loading both in water [31] and air [34] with a simulation scale of 1 : 9.3 did not reveal considerable scale effects of an energetic nature. As in [31], this can be explained by the constancy of the dimensions of the load-bearing unit (fiberglass diameter) in shells of different diameters, which provides for constancy of the elastic energy taken from the fiberglass volume for fiber failure, irrespective of the shell dimensions and the macromechanism of shell failure.…”

“…In experimental studies of simple cylindrical composite shells of revolution under internal explosive loading, it was established that a criterion of their strength can be the ultimate (at the failure threshold) hoop strain of the shell, which under dynamic conditions is 2-2.5 times higher than the similar quasistatic value for the employed composite [13,14,18,21,23,31]. It is shown that the ultimate strain of fiberglass and organic plastic materials depends on the strain rate [24]; at a strain rate of ≈1 000 sec −1 , it approaches the ultimate strain of defect-free fiber.…”

“…The scale effect on the strength of fiberglass shells subjected to internal explosive loading was first studied in [31] on geometrically similar shells filled with water and differing in scale by a factor of 4.4. The results of the experiments showed that for geometrically similar shells with δ/R = 3.7%, the ultimate value of the parameter ξ does not depend on the shell size within the experimental error.…”

Experimental data on the dynamic response and strength of simple shells of fiber composites are used to justify the choice of these materials for the load-bearing shells of blast-proof structures. It is shown that in such structures composites are preferred to homogeneous metal alloys (structural steels) to eliminate strong scale effects of an energetic nature. A criterion for selecting fibers is proposed and justified experimentally, and reinforcement patterns are determined to obtain optimal (in the strength-mass ratio) compositions for the load-bearing shells of blast-proof containers and chambers.
