Incremental layerwise finite element formulation for viscoelastic response of multilayered pavements
This paper provides an incremental layerwise finite element formulation for the viscoelastic analysis of multilayered pavements. The constitutive behavior of asphalt concrete is represented by the Prony series. Layerwise finite element has been shown to provide an efficient and accurate tool for the numerical simulation of laminated structures. Most of the previous research on numerical simula...
متن کاملMechanical characterization of polymers on a nanoscale through AFM nanoindentation: A theoretical study on the time-dependent viscoelastic recovery
The temperature-dependent indent recovery of polymer materials was measured by atomic force microscopy (AFM). A numerical model based on the Boussinesq equations was developed to simulate the viscoelastic indent recovery. Viscoelastic solution of stress and displacement is obtained by using the corresponding principle between elasticity and viscoelasticity. The numerical solution provides resul...
متن کاملCollisional Granular Flows with and without Gas Interactions in Microgravity
We illustrate the convenience of a long-lasting microgravity environment to study flows of granular materials with and without gas interaction. We consider collisional granular flows of nearly elastic identical spheres in an axisymmetric Couette channel featuring two cylindrical moving bumpy boundaries and two flat walls. We review governing equations for these flows, illustrate their solutions...
متن کاملNumerical simulation of granular materials behaviour for unbound base layers used in Algerian pavement structures
Structural analysis of flexible pavements has been and still is currently performed using a multi-layer elastic theory. However, for thinly surfaced pavements subjected to light to medium volumes of traffic, the importance of non-linear stress-strain behaviour of unbound granular materials (UGM’s) requires the use of more sophisticated numerical models for structural design and analysis of such...
متن کاملA Survey on Buckling and Vibrations of a Viscoelastic Beam under Distributed Lateral and Axial Loads
In this paper, based on Kelvin and Linear Standard Solid models, dynamic response and the buckling load of a viscoelastic beam under lateral and axial loads have been determined. The governing equations have been extracted using Euler and Timoshenko theories and their analytical solutions have been obtained by using the eigenfunctions expansion method. Buckling load have been calculated by us...
