Continuum Topology Optimization With Non-Probabilistic Reliability Constraints Based on Multi-Ellipsoid Convex Model

Structural and Multidisciplinary Optimization, 2009
Using a quantified measure for non-probab ilistic reliability based on the multi-ellipsoid convex model, the topology optimization of continuum structures in presence of uncertain-but-bounded parameters is investigated.

Reliability-Based Topology Optimization With Uncertainties

Journal of Mechanical Science and Technology, 2006
This research proposes a reliability-based topology optimization (RBTO) using the finite element method. RBTO is a topology optimization based on probabilistic (or reliability) constraints. Young's modulus, thickness, and loading are considered as the uncertain variables and RBTO is applied to static and eigenvalue problems.
