Size Effects in Elastic Thin Plates

[摘要] The couple stress theory is applied to describe the size effect in elastic thin plates. An extended equation is developed which is available for the bending problem of the plate whose thickness is close to the material length. A comparison with micropolar theory of plates is made.
