With the rapid development of high-performance self-compacting fiber concrete materials, advanced numerical modelling tools are necessary to design optimal materials and structures. A simulation framework that includes numerical modeling of high-performance self-compacting fiber concrete’s mortar flow during the casting process, calculation of local fiber orientation based on deformation gradient in mortar and impact modelling by taking into account local fiber orientation is proposed. A new method for calculation of fiber orientation probability distribution by particle tracking and approximation of particle movements using deformation gradient is proposed. A discrete lattice modelling technique with non-linear, strain-rate and local fiber orientation dependent material constitutive law for numerical impact modelling is proposed. Single-point and three-point concrete casting techniques are numerically simulated and results are compared with experimental measurements showing good agreement. Numerical models showed that fiber orientation and impact resistance of beams are strongly dependent on casting technology for the self-compacting concrete. The proposed numerical model can be used to design efficient concrete casting technologies producing the necessary fiber orientation for load bearing structures.
