Abstract: This paper presents the effect of corrugation profile
geometry on the crushing behavior, energy absorption, failure
mechanism, and failure mode of woven roving glass fibre/epoxy
laminated composite tube. Experimental investigations were carried
out on composite tubes with three different profile shapes: sinusoidal,
triangular and trapezoidal. The tubes were subjected to lateral
compressive loading. On the addition to a radial corrugated
composite tube, cylindrical composite tube, were fabricated and
tested under the same condition in order to know the effect of
corrugation geometry. Typical histories of their deformation are
presented. Behavior of tubes as regards the peak crushing load,
energy absorbed and mode of crushing has been discussed. The
results show that the behavior of the tube under lateral compression
load is influenced by the geometry of the tube itself.
