Studies of the effect of preset square pores on the mechanical properties of Ag nanopsheets under biaxial stretching

Abstract

Abstract This study investigated the mechanical properties of silver nanosheets with preset square pores regarding energy, natural strain, and stress properties. Additionally, the effect of different pore positions on dislocations under symmetrical and asymmetrical loading was analyzed using a model of silver nanosheets with square pores preset under biaxial stretching and molecular dynamics methods. The results revealed that the interaction between shear stress and dislocation can cause fractures, with greater shear stress observed when the pore is closer to the model boundaries. Moreover, the symmetrically positioned pores displayed different mechanical properties under asymmetric loading.
