The properties of hardened concrete structures, fabricated by novel additive manufacturing techniques with fresh concrete, are significantly influenced by the manufacturing process. A numerical framework for the simulation of extrusion processes in additive manufacturing techniques based on layered extrusion is proposed. The flow behavior of fresh concrete is approximated with a regularized Bingham model and in order to deal with large deformation, governing equations are solved via the Particle Finite Element Method.
