Towards a geometry independent traction-separation and angle relation due to large scale bridging in DCB configuration

John Botsis, Georgios Pappas

Traction-separation relations due to large scale bridging in composites are very important in modeling their fracture response. Several works demonstrated that such relations are dependent upon the specimen's stiffness and loading conditions. Experimental ...

Cyclic thermomechanical response of fine-grained soil-concrete interface for energy piles applications

Lyesse Laloui, Melis Sütman, Elena Ravera

Understanding the behaviour of soil-structure interfaces is critical for addressing the analysis and design of energy geostructures. In this study, the interface failure mechanism of energy piles (where a shear band is detached from the surrounding soil th ...

Fast assembly of Galerkin matrices for 3D solid laminated composites using finite element and isogeometric discretizations

Pablo Antolin Sanchez

This work presents a novel methodology for speeding up the assembly of stiffness matrices for laminate composite 3D structures in the context of isogeometric and finite element discretizations. By splitting the involved terms into their in-plane and out-of ...

Elastic properties of self-organized nanogratings produced by femtosecond laser exposure of fused silica

Yves Bellouard, Pieter Vlugter

Under certain exposure conditions, a femtosecond laser beam focused in the bulk of fused silica leads to the formation of self-organized structures consisting of a series of “nanolayers,” parallel to one another. Remarkably, this laser-induced nanoscale an ...

Out-of-plane (flatwise) behavior of through-tenon connections using the integral mechanical attachment technique

Yves Weinand, Aryan Rezaei Rad

This paper aims to characterize the force–deformation response of through-tenon wood-wood connections subjected to out-of-plane (flatwise) loads. Six beech LVL timber specimen groups with variations in the fiber orientation (parallel and perpendicular) and ...

Seismic performance of slender RC U-shaped walls with a single-layer of reinforcement

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida

Reinforced concrete walls are commonly used to resist the lateral loading induced by wind and earthquake actions. While most walls include two vertical reinforcement layers, some regions of the world construct slender, non-rectangular concrete walls with a ...

Experimental Assessment of the Impact of Partial Saturation On the Mechanical Properties of Gas Shales

Lyesse Laloui, Alessio Ferrari, Alberto Minardi

The impact of partial water saturation on the mechanical behaviour of clays and claystones has been widely proved. This work aims at demonstrating that also for gas shales partial water saturation has a significant influ-ence on their stiffness and strengt ...

Cell-free soil bio-cementation with strength, dilatancy and fabric characterization

Lyesse Laloui, Dimitrios Terzis

A multi-disciplinary approach is adopted in the present work towards investigating bio-cemented geo-materials which extends from sample preparation, to microstructural inspection and mechanical behaviour characterization. We suggest a new way to induce “ce ...

Performance assessment of through-tenon timber joints under tension loads

Yves Weinand, Aryan Rezaei Rad

This paper aims to characterize the force-deformation response of through-tenon wood-wood connections subjected to tensile loads. Four beech LVL timber specimen groups with variations in the fiber orientation, and the tab insertion angle (45°, and 60°) are ...
