Abstract

The present work describes the testing to destruction of composite rings made from unidirectional glass-fibre plastic at compression under initial in- ternal blast loading. This destruction happens from bend at compression owing to loss of stability of the radial axisyrninetric movements. It is signif- icant that the initial loading is internal but external pressure is not applied to ring. Large ultimate tensile deformation of material at tension (order of 0.04-0.05) accumulates a quantity of elastic energy in the ring that is enough for its destruction at compression. 1 Introduction The process of a stability loss of the radial axisymmetric form of cylin- drical shell or ring under an oscillatory motion a
