Abstract

Crushing of composite tubes under impact loading has been studied very intensively over the last few
decades. On the contrary, the energy absorption of composite tubes under blast loading is much less
studied, and very limited public literature is available. This paper presents the experimental testing of
a sacri?cial cladding structure, composed of glass/polyester tubes, under blast loading. The composite
tubes show stable and progressive crushing and the peak force transferred to the non-sacri?cial structure
is compared for different con?gurations of the composite tubes. The results also show that the diffraction
of the pressure wave and the skin panel that distributes the blast pressure are critical issues in the set-up of the experiments.
