Dynamics of Functionally Graded Beams on Viscoelastic Foundation
|Published in:||International Journal of Structural Stability and Dynamics, November 2014, n. 8, v. 14|
In the present contribution, the nonlinear dynamics of beams under axial time-dependent excitation is studied. The beams, which rest on a linear viscoelastic foundation, are assumed as axially graded both in terms of geometrical and material properties. The transversal motion equation is derived under two main hypotheses, namely the beams satisfy the requirements of Euler–Bernoulli theory and undergo moderately large deflections (MLDs).
