  The study of atomically thin two-dimensional materials is a young and rapidly
growing field. In the past years, a great advance in the study of the
remarkable electrical and optical properties of 2D materials fabricated by
exfoliation of bulk layered materials has been achieved. Due to the
extraordinary mechanical properties of these atomically thin materials, they
also hold a great promise for future applications such as flexible electronics.
For example, this family of materials can sustain very large deformations
without breaking. Due to the combination of small dimensions, high Young's
modulus and high crystallinity of 2D materials, they have attracted the
attention of the field of nanomechanical systems as high frequency and high
quality factor resonators. In this article, we review experiments on static and
dynamic response of 2D materials. We provide an overview and comparison of the
mechanics of different materials, and highlight the unique properties of these
thin crystalline layers. We conclude with an outlook of the mechanics of 2D
materials and future research directions such as the coupling of the mechanical
deformation to their electronic structure.
