Multi-objective topology optimization design of truss structures based on evidence theory under limited information

open access: yesXibei Gongye Daxue Xuebao, 2023
Uncertainty information is often limited and has great discreteness, how to ensure the structure having good robustness under epistemic uncertainty becomes a technical problem for multi-objective topology optimization design.

Topology Optimization for Minimum Compliance with Material Volume and Buckling Constraints under Design-Dependent Loads

open access: yesApplied Sciences, 2023
Stability is a critical factor in structural design. Although buckling-constrained topology optimization has been investigated in previous work, the problem has not been considered under design-dependent loads.

Inverse Optimum Safety Factor Method for Reliability-Based Topology Optimization Applied to Free Vibrated Structures

open access: yesИнженерные технологии и системы, 2019
Introduction. The classical topology optimization leads to a prediction of the structural type and overall layout, and gives a rough description of the shape of the outer as well as inner boundaries of the structure.

An Iterative Topology Optimization Algorithm That Considers Randomness in Design Parameters

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2012
Topology optimization often incorporates a reliability analysis to take the randomness in the design parameters into account. This strategy is inherently a double-loop procedure due to the probabilistic constraints in optimization.

PBF‐LB/M of Ti‐6Al‐4V: High‐Pressure Solution Treatment and Aging for Applications in a Sustainable Aerospace

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing (AM) allows great geometric freedom for lightweight components. As parts are progressively optimized exploiting potentials in AM leading in smaller material cross sections, high pressure solution treating and aging (STA) treatments show an enormous potential for strongly improving material properties.
