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.

Abstract


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.
