Abstract
A new nonlocal peridynamic contact model is proposed for contact problems accompanied with crack growth. Two long-range peridynamic contact bond forces are developed to study the sticking and sliding frictional contact. A numerical algorithm is proposed to determine the contact surface normal vector and contact condition. Three numerical examples, including contact of two elastic plates, the end loaded split specimens with frictional interface cracks and Kalthoff-Winkler contact tests, are successively investigated to verify and validate the model. Numerical results are compared with the available analytical, finite element method (FEM) and experimental solutions, which demonstrates that the proposed peridynamic contact model can successfully capture both the contact and fracture behaviors.
