Abstract

This paper examines major misconceptions, shortcomings, errors and flaws in the structural topology optimization literature, and tries to clarify the sources of errors. Particular attention is paid to exact analytical benchmark solutions, general properties of optimal structural topologies, and to heuristic features of numerical methods. First a number of controversial issues in the literature are reviewed, and then some fundamental errors with respect to multi-load and probabilistic structural topology optimization are discussed in detail.
