Description:

This project aims to investigate the behaviour of triply periodic minimal surfaces in comparison to other established infill patterns for the use in 3D-printed concrete structures.                   

 The main tasks are as following:                                                              

  • Develop printing strategies and concrete mixes, optimized for printing cementitious TPMS infill patterns.                         
  • Develop refined computational models for the investigation of TPMS infill patterns at the length scale of representative volumes (RVs)                                                               
  • Quantify the elastic behaviour of cementitious TPMS infill patterns under random load configurations, by numerical modelling based on DIC assisted testing                                               
  • Describe the failure behaviour of cementitious TPMS infill patterns under random load configurations, by numerical modelling based on DIC assisted testing                                               
  • Develop simplified anisotropic material models for topological optimization of structures taking into account concrete properties, surface type, and the infill density
