Abstract
A nonlocal elastic behaviour of integral type is modeled assuming that the nonlocality lies in the constitutive relation. The diffusion processes of the nonlocality are governed by an integral relation containing a recently proposed symmetric spatial weight function expressed in terms of an attenua tion function. Starting from the variational formulation associated with the structural bound ary-value problem in the context of nonlocal elasticity, a nonlocal finite el ement model is proposed and a 1D example is proposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
