This study presents an in-depth investigation of interface modeling techniques in ordinary state-based peridynamics (OSB-PD). By performing numerical examples, the accuracy of each technique is investigated by comparison with the finite element solutions for simple bimaterial interface problems. Subsequently, the capabilities of OSB-PD in treating material interfaces with complicated geometries are demonstrated by solving various problems with a single inclusion or multiple inclusions. Finally, a cracked plate containing an inclusion is considered to study effects of the inclusion on dynamic stress intensity factor (DSIF). The OSB-PD shows its huge potential in modeling a structure with multiple defects due to the effectiveness and ease of implementation.
