A Peridynamic Approach for Nanoscratch Simulation of the Cement Mortar
The present study develops a peridynamic approach for simulating the nanoscratch procedure on the cement mortar interface.In this approach,the cement and sand are considered as discrete particles with certain mechanical properties on the nanoscale.Besides,the interaction force functions for different components in the interface are represented by combining the van der Waals force and the peridynamic force.The nanoscratch procedures with the indenter moving along certain direction either parallel or perpendicular to the interface are simulated in this paper.The simulation results show the damage evolution processes and the final damage distributions of the cement mortar under different scratching speed and depth of the indenter,indicating that the interface between cement and sand is a weak area.
