MODELING THE RHEOLOGICAL PROPERTIES OF FRESH CONCRETE USING A 3D FINITE ELEMENT MODEL

Abstract

During the last thirty years, concrete has been industrially mutating from a soft granular medium to a proper non-Newtonian fluid. To benefit from the full potential of the modern fluid concretes such as Self-Compacting Concrete (SCC), prediction tools of the form filling taking into account the properties of the concrete, the shape and size of the structural element and the casting technique are needed. Development of a finite deformation elasto-plasticity model based on the multiplicative decomposition of the deformation gradient is presented. The presented model in this paper includes application of inelastic material properties are specified with the Drucker Prager hardening option.
