Two beams are connected by a Winkler foundation. The wave propagation characteristics like frequency, phase and group velocities are obtained for different wave numbers and material properties. Four frequencies are obtained for functionally graded double-beam system. It is obtained that flexural and axial waves are coupled for FG double-beams.en10.12913/22998624/76697info:eu-repo/semantics/openAccessFunctionally Graded MaterialDouble-BeamWave PropagationPasternak Elastic-FoundationFree-VibrationSystemArticle113143149N/AWOS:000416224600018
