Plane stress problems in nonlocal elasticity: finite element solutions with a strain-difference-based formulation

摘要

An enhanced computational version of the finite element method in the context of nonlocal strain-integral elasticity of Eringen-type is discussed. The theoretical bases of the method are illustrated focusing the attention on numerical and computational aspects as well as on the construction of the nonlocal elements matrices. Two numerical examples of plane stress nonlocal elasticity are presented to show the potentials and the limits of the promoted approach. (C) 2015 Elsevier Inc. All rights reserved.
