Surface viscoelasticity and effective properties of thin-walled structures at the nanoscale

摘要: We discuss the influence of surface viscoelasticity effects on effective properties materials such as bending stiffness plates or shells. Viscoelastic in vicinity can differ from bulk material. This difference influences behavior nanostructural elements. In particular, viscoelastic stresses are responsible for size-depended dissipation nanosized structures. Using extension Gurtin-Murdoch model and correspondence principle linear we derive expressions stress couple resultant tensors shear deformable
