This paper is concerned with the optimal shape of cables subject to external loads only. Design-dependent loads (e.g. selfweight) are assumed to be negligibly small. Consequently, the cable axis is given by the funicular for the prescribed loads.

Surrogate-based aerodynamic shape optimization of hypersonic flows considering transonic performance
Aerospace Science and Technology, 2019Aerodynamic shape optimization of a hypersonic transport aircraft over a wide Mach-number range is challenging. The difficulty is not only associated with the large computational cost of high-fidelity CFD (computational fluid dynamics) simulations but ...

Optimally Directed Shape Generation by Shape Annealing
Environment and Planning B: Planning and Design, 1993The new design technique of shape annealing is introduced. Shape annealing is a variation of the simulated annealing stochastic optimization technique. It produces optimally directed shapes within the language specified by a shape grammar.

Optimality Conditions for Simultaneous Topology and Shape Optimization
SIAM Journal on Control and Optimization, 2003Summary: New optimality conditions are derived for a class of shape optimization problems. The conditions are established on the boundary by an application of the boundary variations technique and in the interior of an optimal domain by exploiting the topological derivative method.

Embedded Optimization for Input Shaping
IEEE Transactions on Control Systems Technology, 2010Traditional input shaping filters are linear mappings between reference input and system input. These filters are often unnecessarily conservative with respect to input and output bounds if multiple references with different amplitudes are applied. This conservatism is due to its offline design and linear mapping.

Isogeometric Shape Optimization on Triangulations
Volume 2B: 42nd Design Automation Conference, 2016The paper presents an isogeometric shape optimization method that is based on Bézier triangles. Bézier triangles are used to represent both the geometry and physical fields. For a given physical domain defined by B-spline boundary, triangular Bézier parameterization can be automatically generated.

A multi-fidelity shape optimization via surrogate modeling for civil structures
Journal of Wind Engineering and Industrial Aerodynamics, 2018Shape optimization serves as a powerful tool to reduce wind effects on buildings. Past studies have demonstrated the superiority of the shape tailoring technique in aerodynamic mitigation through recessing or chamfering building corners, etc. Nonetheless,
