Multi-material rail pad and method for manufacturing same

Véronique Michaud, John Christopher Plummer, Holger Frauenrath, Joël Cugnoni, Oguzhan Oguz, Adrien Julien Demongeot

The invention relates to a rail pad (10, lOa-v, 10α-η) comprising: a) a pad matrix (1) comprising a first material and b) at least one damping element (2) at least partially encapsulated or embedded in the pad matrix (1), said damping element (2) comprisin ...

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

John Botsis, Robin Amacher, Joël Cugnoni, Larissa Sorensen, 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 ...

An efficient method for fiber bridging traction identification based on the R-curve: Formulation and experimental validation

John Botsis, Thomas Gmür, Joël Cugnoni, Guillaume Frossard

Fiber bridging is one of the main toughening mechanisms in mode I interlaminar and intralaminar fracture of laminated composites. Intact fibers exert closing forces on both faces of the crack, restraining crack propagation. An effective identification proc ...

Peri-implant bone adaptations to overloading in rat tibiae: experimental investigations and numerical predictions

John Botsis, Joël Cugnoni, Marco Piccinini

Objectives(i) To assess the effects of mechanical overloading on implant integration in rat tibiae, and (ii) to numerically predict peri-implant bone adaptation. Materials and methodsTranscutaneous titanium implants were simultaneously placed into both tib ...

Numerical prediction of peri-implant bone adaptation: Comparison of mechanical stimuli and sensitivity to modeling parameters

John Botsis, Joël Cugnoni, Marco Piccinini

Long term durability of osseointegrated implants depends on bone adaptation to stress and strain occurring in proximity of the prosthesis. Mechanical overloading, as well as disuse, may reduce the stability of implants by provoking bone resorption. However ...
