Waves generated by ship convoy: Comparison of physical and numerical modeling with in-situ measurements

Anton Schleiss, Giovanni De Cesare, Michael Pfister, Théodora Cohen Liechti, Robin Amacher

A part of the domestic waste of the city of Geneva (Switzerland) is transported with ship convoys on the Rhone River to the waste incineration station. These convoys generate waves, which partially endangers the stability of the river banks and the riparia ...

Enhancing the mechanical performance of composite corners through microstructural optimization and geometrical design

Véronique Michaud, Robin Amacher, Vincent Marc Varanges, Valentin Rougier, Yann Albert Gérard Lebaupin

Processing carbon fiber-reinforced composites into corner sections through compression molding poses challenges due to the limited flowability of continuous prepregs, resulting in reduced curved beam strength (CBS). The use of discontinuous plies was explo ...

Towards aerospace grade thin-ply composites: Effect of ply thickness, fibre, matrix and interlayer toughening on strength and damage tolerance

John Botsis, Joël Cugnoni, Larissa Sorensen, Robin Amacher, Sébastien Kohler

Thin-ply composites represent a promising approach to further improve the performance of carbon fibre composite structures thanks to their ability to delay the onset of matrix cracking and delamination up to the point of fibre dominated failure. However, t ...

Thin ply composites: Experimental characterization and modeling of size-effects

John Botsis, Joël Cugnoni, Larissa Sorensen, Robin Amacher

Thin-ply composites are rapidly gaining interest in the composite industry, not only because of the larger design possibilities that they offer, but also because of positive size effects that have been shown to improve performance in various loading condit ...

Wave-reducing Stern Flap on Ship Convoys to Protect Riverbanks

Anton Schleiss, Giovanni De Cesare, Michael Pfister, Théodora Cohen Liechti, Robin Amacher

Inland navigable waterways are significant in cargo transport and leisure activities. In parallel, these channels and rivers often suffer from the ship traffic, as the generated waves may damage waterway banks, along with their riparian fauna. As a consequ ...

Transverse cracking in the bulk and at the free edge of thin-ply composites: experiments and multiscale modelling

John Botsis, Robin Amacher, Joël Cugnoni, Sébastien Kohler

Thin-ply composites were shown to exhibit significantly delayed transverse cracking, but the linear onset of damage scaling with ply thickness reported by Amacher et al. (2014) did not correspond to the established LEFM based in situ strength model. This s ...

Notch nonlinearities in pseudo-ductile composite laminates: A novel LE/HE sublaminate design

Robin Amacher

Attempts to achieve pseudo-ductility in quasi-isotropic (QI) thin-ply laminates have traditionally relied on stacking [LE/HE/LE] sublaminates, with LE representing low-elongation and HE high-elongation. However, the increase in effective ply thickness led ...
