The bond strength between layers of printed concrete is one of the critical features to control for robust and safe structural applications of 3D printing. This feature is however influenced by various factors, such as the time between printed layers, the environmental conditions (humidity, temperature), geometrical features of the layer and nozzle, and so on. The goal of this research is to establish the extent to which these factors influence the bond strength by means of an experimental program. In the past, various experimental methods have already been developed at TU/e, which provide a starting point for this research. The experimental results will be collected and (statistically) analyzed. Next, they will be used as input for a numerical (FEM) model of the bond strength in printed concrete. Once validated, such a FEM model can be used for structural analyses of (complex) 3D printed geometries.
For this graduation project, affinity with experimental testing and numerical (FEM) modelling is desired. This project is linked to an ongoing research program of EAISI, Eindhoven Artificial Intelligence Systems Institute.
