Abstract
In this paper, a peridynamic model for simulating the dynamic fracture in layered engineered cementitious composites (LECC) is applied. The model takes into account the location information of the fibers as well as the distribution form. In addition, numerical simulations of LECC beams under four-point bending are carried out. The effects of notch size and fiber volume fraction are investigated. The numerical results show that the notch size and gradient distribution of fiber volume fraction affect the crack propagation pattern, which can help to understand the dynamic fracture behavior of engineered cementitious composites.
