Abstract
In this paper, MPS method was applied to fluid analysis of fresh concrete with vibration. MPS method is one of the particle method, and it is suitable for the simulation of moving boundary or free surface problems and large deformation problems. The constitutive equation of fresh concrete is assumed as Bingham model. In order to set fluidity change of fresh concrete based on the decrement of the acceleration, the Bingham model is supposed to be the yield stress and the plastic viscosity of fresh concrete that decreased most in the neighborhood of the vibrator.
To evaluate verification of compactability of fresh concrete, numerical analysis examples of compaction at the part of haunch section of wall were performed. As a result, it was found that the MPS method was suitable for the simulation of compaction of fresh concrete with vibration.
