Bedding structure slate can be always observed in civil and mining engineering in recent years，their physical and mechanical properties are significantly controlled by the existing bedding planes，which are generally considered as weak links that can cause various geological disasters.The fracture behavior of bedding structure slate under dynamic loading is therefore a critical issue for the selection of blasting parameters，stability analysis of rock mass，collapse and burst disaster prevention in tunnel，drift，and other underground structures.In order to investigate the effects of the inclination angle of bedding plane and impact velocity on the dynamic fracture behavior of bedding structure slate，the dynamic impact test and numerical simulation method inserted cohesive element were conducted on the notched semicircular bending（NSCB） specimens by a split-Hopkinson pressure bar（SHPB）system.Tests of NSCB specimens under static loading were conducted for comparison，and the inserted cohesive element method was also used to develop the numerical model of layered NSCB specimens under dynamic loading.The fracture initiation and propagation process of the layered specimen under varied loading conditions were modeled.The results show：（1）Impact velocity and the inclination angle of bedding plane has obvious influence on the crack propagation，and three typical cracking paths can be found for NSCB specimens under both static and dynamic loading.（2）The crack propagates along the bedding plane and then directly propagates to the loading point，the cracking path evidently exhibits dependence on the impact velocity and the inclination angle of bedding plane.For specimens under static loading，the dominated crack is more likely to propagate along the bedding planes while the cracks tend to ignore bedding planes as the impact velocity or the inclination angle of bedding plane increases.At the same time，the crack length along the bedding plane is considerably reduced under dynamic loading than under static loading.（3）It is obvious that the impact velocity and the inclination angle of bedding plane have important influence on fracture toughness，it becomes larger with the increasing impact velocity or the inclination angle of bedding plane.
