Abstract
The robust topology optimization approach with uncertainties of loading magnitude and direction is investigated for continuum structures. The input loadings with uncertain magnitude and direction are decomposed using the second order Taylor series expansions, and then the response of statistical response of compliance is calculated using perturbation analysis method. The robust topology problem with minimize the compliance is solved using the modified SIMP (Solid Isotropic Material with Penalization) algorithm. The efficiency of the proposed methodology is verified using the examples of cantilever beam.
