The application of reduced space harmonic balance method for the nonlinear vibration problem in rotor dynamics

H Liao - Mechanics Based Design of Structures and Machines, 2019 - Taylor & Francis
The reduced space harmonic balance method is demonstrated to find the maximum
vibration responses of rotor systems. Within the reduced space SQP method, transition from …

Local stress‐constrained and slope‐constrained SAND topology optimisation

D Munro, A Groenwold - International Journal for numerical …, 2017 - Wiley Online Library
We study the alternative 'simultaneous analysis and design'(SAND) formulation of the local
stress‐constrained and slope‐constrained topology design problem. It is demonstrated that …

On design-set restriction in SAND topology optimization

D Munro, AA Groenwold - Structural and Multidisciplinary Optimization, 2018 - Springer
We study design-set restriction—ie, the issue of nonexistence of solutions, mesh-
dependence, and local minima—in the alternative SAND ('simultaneous analysis and …

A direct approach to structural topology optimization

DP Munro - 2017 - scholar.sun.ac.za
This dissertation addresses various topics that emerge from the unification of conventional
structural optimization—based on 'sequential approximate optimization'(SAO)—with the …

Singular, large-scale solutions in local stress-constrained topology optimization

D Munro, A Groenwold - … Optimization: Proceedings of the 12th World …, 2018 - Springer
In this paper, the union of sequential approximate optimization (SAO) and the 'simultaneous
analysis and design'(SAND) formulation of the local stress-constrained topology …
