This project is aimed to elucidate the experimentally measured exceptional elastic properties of two-dimensional (2D) Bismuth Telluride (Bi2Te3) nanosheets via computational means. Particularly, finite element analysis will be employed to model the details of stress field and deformation field distribution within the 2D nanosheets under an experimental setup. Different parameters including the thickness and diameter of circular, suspending 2D nanosheets, and the amount of a point force applied to a 2D nanosheet will be investigated. These results will be directly connected with to L. Guo et at.’s experimental report work by calibrating the effect of various mechanical loadings and boundary constraints. By understanding elastic behaviors of these 2D nanosheets using finite element analysis, this work will advance the understanding of elastic field in a 2D nanosheet of Bi2Te3 and other van der Waals family materials and potentially facilitate their application in strain engineering.
