Molecular dynamics study of the interfacial debonding due to cylindrical nano-inclusion

Abstract eng:
The corresponding s ress-strain relation and the nucl ated void volu e fraction of t e composite m terial are monitored during uniaxial loading using the modif ed embedded atom model (ME M). Due to the presence of the inclusion-matrix interface, both he effect of energy minimiz tion and confi uration relaxati n are investigated to ensure an initial physical bonding of the two materials. During the stretching of si ulation box, the localized decohesion tends to initiate on the portion of the interfacial circu ference facing the loading direction. The simulation results also reveal tha the simulation size and strain rate influence t e onset of interfacial decohesion while the thickness of the imulation box has virtually no i pact. The largest simulation size contains an inclusion up to 105. nm in diameter with a total of 10.6 million a oms. An enlarg d simulation size not only lower the yield stress but also the strain of decohesion nitiation
