How contained hydraulic fractures emerge from layers of alternating fracture toughness

Brice Tanguy Alphonse Lecampion, Carlo Peruzzo

Hydraulic fractures are used to enhance the hydrocarbon production from low permeability rocks and to measure the minimum in-situ principal stress in rock formations. In these cases, the fracture growth above (or below) the formation of interest is a key m ...

Life cycle assessment of an innovative bio-based unsaturated polyester resin and its use in glass fibre reinforced bio-composites produced by vacuum infusion

Mateus De Assunção Hofmann

Oil -based polymeric resins are widely used in the manufacture of fibre -reinforced polymer (FRP) composites, contributing up to 70 % to their total weight. In an effort to reduce the dependence on oil -based feedstock, bio-based alternatives are being inc ...

An Experimental Approach for the Design of Uni-axial Fiber Reinforced Dielectric Elastomer Actuators

Julian Asboth, Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Stefania Maria Aliki Konstantinidi, Armando Matthieu Walter, Simon Holzer

Dielectric Elastomer Actuators (DEAs) are a type of soft actuators, generating mechanical displacement when an electric stimulation is applied. DEAs can be described as compliant capacitors, and when a voltage is applied, a compressive Maxwell stress will ...

Laser powder bed fusion of Fe-based shape memory alloys for novel structural metamaterials and "smart" structures

Irene Ferretto

Laser powder bed fusion (LPBF) is a powder-based additive manufacturing (AM) technique, which shows great potential in the production of complex-shaped parts with unprecedented design freedom. In addition, it allows for an active manipulation of the micros ...

Metallosupramolecular polymers as precursors for platinum nanocomposites

Emad Oveisi

Nanocomposites comprising a polymer matrix and metallic nanoparticles (NPs) can merge the structural features of the matrix material with the functional characteristics of the NPs. While such materials are promising for a wide range of applications, their ...

Neutron Bragg edge imaging for strain characterization in powder bed additive manufacturing environments

Roland Logé, Reza Esmaeilzadeh, Claire Navarre, Shieren Sumarli

Spatially resolved studies of crystalline structures, e.g. lattice spacings, are enabled by recording the transmitted spectra in neutron Bragg edge imaging. The recorded signals are, however, a result of through-thickness averaging of the probed specimen i ...

Low-damage steel structures for enhanced life-cycle seismic performance

Dimitrios Lignos, Martina Paronesso

During an earthquake, steel frame buildings with bracings are prone to high absolute floor acceleration demands, thereby causing damage to acceleration-sensitive non-structural elements and building content. Inelastic deformations in steel bracings and/or ...

Review of fatigue of bulk structural adhesives and thick adhesive joints

Anastasios Vassilopoulos

Fatigue of structural adhesives has been investigated through joints and a little number of works investigate bulk adhesive behaviour itself. Aerospace and automotive engineering focuses more on joint configuration studies, which are correlated with practi ...

The mechanical behaviour and failure modes of volcanic rocks: a review

Marie Estelle Solange Violay

The microstructure and mineralogy of volcanic rocks is varied and complex, and their mechanical behaviour is similarly varied and complex. This review summarises recent developments in our understanding of the mechanical behaviour and failure modes of volc ...

Micro-mechanical insights into the dynamics of crack propagation in snow fracture experiments

Johan Alexandre Philippe Gaume, Grégoire Bobillier

Dry-snow slab avalanches result from crack propagation in a highly porous weak layer buried within a stratified and metastable snowpack. While our understanding of slab avalanche mechanisms improved with recent experimental and numerical advances, fundamen ...

Numerically-based method for fracture characterization of Mode I-dominated two-dimensional delamination in FRP laminates

Thomas Keller, Anastasios Vassilopoulos, Aida Cameselle Molares

A new numerically-based method suitable for determining the total strain energy release rate (SERA) involved in two-dimensional (2D) Mode I-dominated delamination under opening loads in FRP laminates is presented. The method is based on the mutual dependen ...

Time-dependent strength of concrete in compression and shear

Darko Tasevski

Sustained load actions are permanently present in concrete structures, as for example self-weight and dead loads on bridges or soil pressure on cut-and-cover tunnels. These actions may increase throughout a structure's lifetime, for instance after refurbis ...

Wide-field imaging of cortical neuronal activity with red-shifted functional indicators during motor task execution

Silvestro Micera

Genetically encoded calcium indicators (GECIs) can be used to monitor the intracellular concentration of free calcium in populations of neurons. GECIs with long emission wavelengths are particularly attractive for deep tissue microscopy in vivo, and have t ...
