ABSTRACT = {In this study, a new bond-based peridynamic model is proposed to
describe the dynamic properties of ceramics under impact loading. Ceramic materials show pseudo-plastic behavior under certain compressive loadings with high
strain-rate, while the characteristic brittleness of the material dominates when it is
subjected to tensile loading. In this model, brittle response under tension, softening plasticity under compression and strain-rate effect of ceramics are considered,
which makes it possible to accurately capture the overall dynamic process of ceramics. This enables the investigation of the fracture mechanism for ceramic materials, during ballistic impact, in more detail. Furthermore, a bond-force updating
algorithm is introduced to perform the numerical simulation and solve the derived
equations. The proposed model is then used to analyze the dynamic response of
ceramics tiles under impact loading to assess its validity. The results of damage
development in ceramic materials are calculated and compared with the experimental results. The simulation results are consistent with the experiments, which
indicates that the proposed rate-dependent peridynamic model has the capability
to describe damage propagation in ceramics with good accuracy. Finally, based on
a comparison between simulation and experimental results, it can be concluded
that the damage results are in better agreement with experimental results than
non-ordinary state-based peridynamic method.},
