Researchers at the University of Hong Kong have developed a method to control and assess instability in two-dimensional (2D) materials. Using a “push-to-shear” strategy, they achieved in situ observation of in-plane shear deformation, allowing for controllable tuning of instability in 2D materials like graphene and molybdenum disulfide. This method combines theoretical analysis and molecular dynamics simulations to understand multi-order instability, enhancing the mechanical application of 2D materials. The approach has significant implications for engineering applications and the development of new mechanical measurement platforms.
