摘要：
Li et al. (2016) studied free vibration problem of nonlocal strain gradient beams made of functionally graded material. They concluded that when the two material length parameters are the same, the classical results can be obtained. However, the non-classical shear force resultant approaches to infinity for ea = l, indicating that the shear force resultant given by the authors is meaningless. This Comment focuses on the solution of the inconsistence. (C) 2017 Elsevier Ltd. All rights reserved.
