An Analytical Method to Predict the Structural Behavior of Timber-Concrete Structures With Brittle-to-Ductile Shear Connector Laws

Timber-Concrete Composite (TCC) structures allow taking synergistic advantage of the properties of both materials to optimize the overall performances in terms of lightness, slenderness, acoustic insulation, vibrational behaviour and environmental footprin ...

Two-dimensional crack growth in FRP laminates and sandwich panels

Aida Cameselle Molares

Fiber-reinforced polymer (FRP) composite materials are currently being selected for the design of lightweight and efficient structural members in a wide number of engineering applications. Sandwich panels with glass fiber-reinforced polymer (GFRP) face she ...

Micromechanical study on the origin of fiber bridging under interlaminar and intralaminar mode I failure

John Botsis, Georgios Pappas, Fernando Naya Montans

Fiber reinforced polymers (FRPs) subjected to mode I fracture show important toughening due to the development of large scale bridging (LSB). Experimental studies of this phenomenon in unidirectional carbon/epoxy laminates using double cantilever beam spec ...

Behavior of prestressed CFRP plates bonded to steel substrate: Numerical modeling and experimental validation

Elyas Ghafoori, Ardalan Hosseini, Masoud Motavalli

In recent years, retrofitting of steel structures has emerged as a major issue in structural engineering and construction management. As the adhesive bond is often the critical aspect controlling the actual performance of steel profiles externally strength ...

Crushing and intrusion resistance improvement of aluminum beams by carbon/epoxy composite patches

Véronique Michaud, Jonathan Friedli, Mathieu Piccand, Baris Çaglar, Yann Albert Gérard Lebaupin

This study investigates the intrusion and crushing performance of hybrid fiber metal laminates based on aluminum and carbon fiber reinforced polymers, in comparison to reference aluminum parts, made from AA6451 or AA7075 automotive grade alloys. A first se ...

Multiscale experimental characterisation and modelling of transverse cracking in thin-ply composites

Sébastien Kohler

In this work, the damage dependency on ply thickness is investigated experimentally for three different thin-ply CFRP quasi-isotropic laminates, with constituents spanning a large range of properties. It is shown that free edge damage mechanisms, observed ...

Modelling Workflow for Segmented Timber Shells using Wood-wood Connections

Yves Weinand, Julien Gamerro, Petras Vestartas, Nicolas Henry Pierre Louis Rogeau

This paper presents a modelling method based on planarization for double-curved segmented timber shell made from quad polygons and assembled by wood-wood connections. The inspiration is taken from timber dome structures, where solid timber walls were built ...

Assessment of capillary phenomena in liquid composite molding

Véronique Michaud, Baris Çaglar, Feyza Karasu Kiliç, Cem Tekin

The interplay between capillary and viscous forces plays a significant role for optimal part quality in fiber-reinforced composites manufactured by Liquid Composite Molding (LCM); these are however difficult to analyze during flow. Two approaches are propo ...

Load history effects in fibre-reinforced polymer composite materials

Abdolvahid Movahedirad

Today, it is widely accepted that fatigue is one of the most common failure mechanisms in structural components, and pure static failure is rarely observed. Engineering structures are subjected to complex mechanical fatigue loading histories, which cause d ...

Influence of the stacking sequence on the low-energy impact resistance of flax/PA11 composite

Yann Albert Gérard Lebaupin

In this paper, the low-energy impact behavior of a fully biobased composite made of bio-sourced polyamide 11 resin reinforced with flax fibers was investigated. Different composite laminates were studied in order to determine the stacking sequence effects ...
