Abstract

Employing the modified phase-field-crystal (MPFC) model, we investigated the size effects of shear deformation response on nano-single crystals by examining the elastic strain distribution at atomistic scales. Here, three specimens with different aspect ratios are explored. Three types of shear deformation behavior have been found, namely, bending, simple shear and the mixed-mode based on the competition of bending and shearing. Further, a size scale analysis indicates that the slope of the shear strain response curve decreased dramatically as the aspect ratio changed from 1 to 0.125. However, when the ratio increased from 1 to 8, the slope increased slowly until saturated.
