Analytical Study on Flow behaviors of Fresh Concrete with Viscous Granular Materials Model and Smoothed Particle Hydrodynamics

摘要

In this paper, flow simulation method of fresh concrete wasrnproposed on the basis of SPH approach, VGM model, andrnvisco-plastic slippage resistance model. Then, the L-flow tests ofrnthree fresh mortar mixtures were performed to verify the validityrnof the proposed numerical method.rnThe VGM model can describe the nonlinear, loadingrntime-dependent, and pressure-dependent characteristics of thernflow behaviors of fresh concrete. Therefore, the numerical resultsrnusing the VGM model are more consistent with the experimentalrnresults than Bingham model for lower fluidity fresh concrete.
