Abstract

3D printing is poised to become a disruptive force for the terrestrial construction industry, and it is also the most likely technology that will make possible the safe and reliable development of extraterrestrial infrastructure. While more and more researchers are working on developing novel and appropriate mixes, as well as 3D printing technologies, only a few and somewhat limited computational models are available in the literature for the design and analysis of 3D printed structures. Nevertheless, engineers need simulation tools for the design and optimization of any structure, including 3D printed. The main objective of this paper is to highlight the formulation of the discrete fresh concrete model (DFCM). DFCM is a particle-based fresh cementitious material model that simulates the rheological and mechanical behavior of material accurately before, during, and after printing to optimize the printing process and the material flow. For DFCM, the interaction among spherical particles is governed by visco-plastic constitutive equations, which, unlike conventional particle models that use force-displacement relationships, are based on stress-strain relationships. This allows a mathematical formulation enabling a seamless transition from the description of fresh concrete to the one of hardened concrete.
