Abstract The aim of this work is to employ a modified cell-based smoothed finite element method (S-FEM) for topology
optimization with the domain discretized with arbitrary polygons. In the present work, the linear polynomial basis
function is used as the weight function instead of the constant weight function used in the standard S-FEM. This
improves the accuracy and yields an optimal convergence rate. The gradients are smoothed over each smoothing
domain, then used to compute the stiffness matrix. Within the proposed scheme, an optimum topology procedure
is conducted over the smoothing domains. Structural materials are distributed More >
