Experimental and numerical free vibration analysis of industry-driven woven fibre laminated glass/epoxy composite beams.

The present study involves frequency-driven exploration of bi-directional, industry-driven, laminated composite glass/epoxy beams by experimental and finite element analysis. The experimental vibration responses were ensured through a vibration first Fourier transform (FFT) analyzer. The finite element predictions were made using MATLAB platform by developing a programmable computer code accounting for shear deformation. The results conclude that the free-vibration finite element predictions for glass/epoxy beams are sensitive to effects of different boundary conditions and span-to-thickness ratios. The present study will assist in our understanding of modal behaviour towards design and service of laminated beams in the frequency domain and can serve as experimental benchmark results.
