Peridynamics is a particle method, where a material failure is expressed by a breakage of the interparticle bonding. The NOSB peridynamics is a variant of the peridynamics which allows us to implement any kind of constitutive law to the peridynamics framework. In the present paper, we report the NOSB peridynamics results for a contact and fracture simulation using unstructured particle arrangement, required so as to properly treat contact problems. To deal with the ununiform particle arrangement, we incorporated the weight function employed in the Hamiltonian particle dynamics into the peridynamic framework. This treatment allows us to easily perform the simulation using the unstructurally positioned particles without any difficulty related to the partial volume estimation required in the original formulation. The results show that this approach is effective to tuckle to the contact problem and it works even for the fracture simulation.
