Abstract This paper addresses the problem of structural shape and topology optimization. A level set
method is adopted as an alternative approach to the popular homogenization based methods. The paper focuses
on four areas of discussion: (1) The level-set model of
the structure’s shape is characterized as a region and
global representation; the shape boundary is embedded in
a higher-dimensional scalar function as its “iso-surface.”
Changes of the shape and topology are governed by a
partial differential equation (PDE). (2) The velocity vector of the Hamilton-Jacobi PDE is shown to be naturally
related to the shape derivative from the classical shape… More >
