A unified stochastic framework for robust topology optimization of continuum and truss-like structures Vrije Universiteit Brussel
In this paper a framework is introduced for robust structural topology optimization for 2D and 3D continuum and truss problems. The uncertain material parameters are modelled using a spatially correlated random field which is discretized using the Karhunen-Loève expansion. Spectral stochastic finite element method is used, with a polynomial chaos expansion to propagate uncertainties on the material characteristics to the response quantities. In ...
