A novel triple-structure coding to use evolutionary algorithms for optimal sensor placement integrated with modal identification Struct. Multidisc. Optim. (IF 3.9) Pub Date : 2024-03-19
Abstract Optimal sensor placement (OSP) is a challenging combinatorial problem commonly addressed using Genetic algorithms (GAs), which are well suited to discrete problems. However, coding the problem can be difficult and often requires manual modifications during optimization. On the other hand, applying optimization methods designed for continuous problems to OSP is problematic due to its discrete

One-shot procedures for efficient minimum compliance topology optimization Struct. Multidisc. Optim. (IF 3.9) Pub Date : 2024-02-29
Abstract In this paper, a one-shot approach for minimum compliance topology optimization is investigated. In the convex case of variable thickness sheet optimization, an optimality criteria scheme with a single step of an iterative state solver converges to the same solutions as an accurate procedure. This remarkable behavior is explained by the crucial role of the geometric multigrid preconditioner

Abstract This note communicates a simple modification of the optimality criteria (OC) design update—as found in well-known Matlab implementations of the classical topology design problem—to an update based on a quadratic program (QP) with a single linear constraint. This QP update is a special case of the dual of Falk, which in general accommodates multiple constraints, as discussed in the Appendix

Abstract Compliant mechanisms with multiple input loads and output ports are commonly applied in micro-electromechanical systems (MEMS), while compliant mechanisms under design-dependent pressure loadings (such as pneumatic or hydraulic) can generate smooth and compatible deformations. Combining these two types of problems, we propose the design problem of compliant mechanisms under multiple design-dependent

Combined shape and topology optimisation of shell structures using FE-based parameterisations Struct. Multidisc. Optim. (IF 3.9) Pub Date : 2024-02-12
Abstract Studies that optimise both the shape and topology of shell structures typically utilise CAD parametrisations to describe the geometry of the shell and density-based methods to characterise its material layout. Relying on CAD-based approaches has the advantage that only a few design variables, usually the control points of the surface, are included in the shape optimisation problem, thereby
