Abstract :
In this study, we apply the newly derived finite Eshelby tensor in a variational multiscale formulation to
construct a smart element through a more accurate homogenization procedure. The so-called Neumann–
Eshelby tensor for an inclusion in a finite domain is used in the fine scale feedback procedure to
take into account the interactions among different scales and elements.
Numerical experiments have been conducted to compare the performance and robustness of the
new element to earlier formulations. The results showed that the smart element constructed via the
Neumann–Eshelby tensor of a finite domain provides better numerical accuracy than that constructed
via the Eshelby tensor of an infinite domain. Moreover, it can relieve volumetric locking
