Vortex shedding from a composite hydrofoil: Experimental evidence of a novel "partial lock-in"

Mohamed Farhat, Thomas Antoine Nicolas Berger, Qin Wu, Yunqing Liu

Lock-in is of great importance in many engineering applications due to its practical implications for structural safety. The influence of composite bend-twist coupling on the wake dynamics and vortex-induced vibration around a carbon fiber composite hydrof ...

Environmental and Life-Cycle Cost Evaluation of a Composite Timber-UHPFRC Bridge

Eugen Brühwiler, Numa Joy Bertola

Ultra-High-Performance Fibre Reinforced Cementitious Composite (UHPFRC) has recently been used to design lightweight structures and strengthen existing ones, with more than 300 applications in Switzerland. Several composite timber-UHPFRC bridges have been ...

Experimental testing and structural analysis of composite tile – reinforced concrete domes

Savvas Saloustros

Conventional formworks for concrete curved shells either are expensive, complex and wasteful or have formal restrictions. Using tile vaults (also known as timbrel, Guastavino, thin-tile or Catalan vaults) as stay-in-place formwork for concrete shells could ...

On algebraic twists with composite moduli

Philippe Michel, Yongxiao Lin

We study bounds for algebraic twists sums of automorphic coefficients by trace functions of composite moduli. ...

Dordrecht2023

Reinforced concrete and steel (RCS) structures are an exceptional combination when exploited thoughtfully; the advantages of composite structures over pure steel or reinforced concrete have been demonstrated through studies and real tests. Nonetheless, the ...

Origami-inspired carbon fiber-reinforced composite sandwich materials - Fabrication and mechanical behavior

Thomas Keller, Yuntong Du

A folding fabrication method inspired by origami for carbon fiber-reinforced composites to fabricate three-dimensional structures is presented. PMI foams serve as substrates, making it possible to manufacture this kind of origami-inspired composite sandwic ...

A "combi-encapsulant" for enhanced performance of glass-free lightweight crystalline silicon solar PV modules

Christophe Ballif, Alessandro Francesco Aldo Virtuani, Fabiana Lisco

Lightweight crystalline silicon (c-Si) PV modules with a weight of 5kg/m(2), by substituting the typical front glass with a thin polymer sheet and the standard back sheet by a composite sandwich structure are presented here. With this work, we propose the ...

Minimal mass design of active tensegrity structures

Yafeng Wang

Tensegrity structures have been widely utilized as lightweight structures due to their high stiffness-to-mass and strength-to-mass ratios. Minimal mass design of tensegrity structures subject to external loads and specific constraints (e.g., member yieldin ...
