Plant fibers have enormous potential for enhancing concrete's impact resistance due to their exceptional toughness and ductility. Nevertheless, theoretical studies on the impact properties of plant fiberreinforced concrete (PFRC) are still relatively few. Thus, it is crucial to investigate from a theoretical standpoint how plant fibers affect concrete's impact properties. Based on the ...
