Mechanical properties for nanomaterial are sensitive to the dimension, surface, and other physical properties of the nanomaterial, so they can be effectively tuned in varying degrees. As a result, nanomaterials have plenty of novel properties like super-hardness, ultra-light, extreme fracture strength, etc. These fantastic nanomechanics phenomena have attracted a worldwide research interest in the past few decades. The article concisely reviews some key progresses in the nanomechanics field in 2019.
