increased in complexity. Recently, Lee (2014) developed an algorithm named ViscoWave to simulate
pavement dynamics under Falling Weight Deflectometer (FWD) loading. ViscoWave uses continuous integral transforms which are able to accurately
simulate the dynamics response of the pavement.
Similarly, Yan et al. (2014) evaluated wave propagation using an analytical layer-element approach
under the FWD loading conditions. Using the
global stiffness matrix equation from the multilayered pavement, a realistic solution is obtained
through the Fourier-Hankel transform. Xu and
Prozzi (2014) compared static against viscoelastic
wave propagation analysis techniques using FEM.
Findings for frequency spectrum, modal shape,
deflection, stress, and strain were evaluated. It
was found that wave propagation contributed to
the time delay of deflections. In addition, including viscoelastic properties produced more accurate
deflections and tensile stresses when compared to
quasi-elastic analysis.Read More
