Micromechanical response of pure magnesium at different strain rate and temperature conditions: twin to slip and slip to twin transitions

Roland Logé

The strain rate (epsilon ) and temperature ( T ) dependent mechanical response of single crystal magnesium (Mg) micropillars compressed along the [ 2 over line 110 ] direction ( a-axis) is investigated from room temperature to 573 K and from 10-3 to 100 s- ...

Failure mechanism of fine-grained soil-structure interface for energy piles

Lyesse Laloui, Elena Ravera

The response of the soil-structure interface can significantly affect the performance of any geotechnical structure. Thermal cycles are a new factor that influence the response to all structures that have an energy function in addition to the structural on ...

Effect of water on sandstone's fracture toughness and frictional parameters: Brittle strength constraints

Marie Estelle Solange Violay, Corentin Jean-Marie Rémi Noël

Water presence causes a dramatic reduction of sandstone strength. Under compressive stress conditions, the strength of a rock sample is controlled by frictional parameters and the fracture toughness of the material. Here, we report fracture toughness, fric ...

Atomic scale investigations of fracture in metal alloys

Eleanor Yi Kei Mak

The demand for metal alloys with superior structural performance in industrial applications continues to increase, as does the need for more-energy efficient materials and methods. Many materials that are otherwise attractive for structural applications ar ...

Coupling between cohesive element method and node‐to‐segment contact algorithm: Implementation and application

Guillaume Anciaux, Mohit Pundir

In materials, the evolution of crack surfaces is intimately linked with the self-contact occurring between them. The developed contact forces not only mitigate the effect of stress concentration at crack tip but also contribute sig- nificantly to the trans ...

Experiments and numerical modelling on angle-ply laminates under remote mode II loading

John Botsis, Georgios Pappas, Niels Pichler, Charlie Joseph Simon Blondeau

Delamination is a very frequent damage mechanism that affects the integrity of laminated composites. In this study, the effect of ply orientation on crack growth resistance was analyzed for three different anti-symmetric interfaces (+/- 30 degrees, +/- 45 ...

Influence of Residual Stresses on Fatigue Response of Welded Tubular K-Joints

Claire Acevedo

Seeking light and transparent bridge designs, engineers and architects have found an efficient and artistic way to fulfill their requirements: steel tubular bridges. In these modern tubular truss bridges, welded K-joints have been shown to be critically su ...

Fundamentals of desiccation cracking of fine-grained soils: experimental characterisation and mechanisms identification

Lyesse Laloui, Hervé Péron

This paper presents the results of a comprehensive experimental study of the desiccation of fine-grained soils. Air-drying of initially saturated soil slabs in controlled conditions is investigated, by performing three kinds of tests: free desiccation test ...

Shear strength of members without transverse reinforcement as function of critical shear crack width

Aurelio Muttoni, Miguel Fernández Ruiz

This paper investigates the shear strength of beams and one-way slabs without stirrups based on the opening of a critical shear crack. The shear-carrying mechanisms after the development of this crack are investigated. On this basis, a rational model is de ...
