Abstract

This work examines the problem of oscillating boundaries in density-based topology optimisation algorithms based on B-spline hyper-surfaces. We compare recent developments in the different approaches proposed in the literature and attempt to find a relatively easy and robust method to obtain smooth optimal solutions by minimising the number of design variables and the associated computational effort.
