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