Abstract: Experimental investigations carried out to analyze the effect of axial compression on buckling and dynamic behaviour of laminated composite beam is presented. Typical load vs deflection curve for the composite beam under axial compression load is used to evaluate the critical buckling load. Followed by this, the axial compression load is varied in fraction of critical buckling load and corresponding variation in first three transverse bending natural frequencies are analyzed. Influence of uni-directional, bi-directional and pre-preg reinforcement on buckling and natural frequencies also studied. It is found that buckling strength of the pre-preg composite beam is significantly higher than the other two types of beam studied. It is also observed that increase in axial compression load reduces natural frequencies of the beam and the effect is significant for the fundamental mode. � 2018 Author(s).
