Characterization of viscoelastic properties of PDMS silicon rubbers

In this project we target a desired viscoelastic properties of PDMS for the application of thin wall membrane uses as a container to support soft test sample biomaterials during mechanical compression tests. The biocompatible PDMS membrane is produced by a ...

Bioresorbable Nanocomposite Foams for Bone Tissue Engineering

Claire Diane Delabarde

The present work forms part of an ongoing effort at the Laboratory of Polymer and Composite Technology (LTC) to develop novel solvent-free processing methods for next generation resorbable porous scaffolds for bone replacement, based on supercritical carbo ...

Shear Buckling Resistance of GFRP Plate Girders

Thomas Keller, Anastasios Vassilopoulos, Behzad Dehghan Manshadi

Thin webs of glass-fiber-reinforced polymer (GFRP) girders are sensitive to shear buckling, which can be considered an in-plane biaxial compression-tension buckling problem, according to the rotated stress field theory. An extensive experimental study was ...

A multi-scale multi-physics model of soil drying

Lyesse Laloui, Hervé Péron

Drying shrinkage is modeled at a microscale as a two-stage process of deformation and evacuation of a two-tube vessel system, based on porosimetry evolution. In the first stage water flow is driven by an external evaporation flux. Flow is associated with a ...

Small strain mechanical properties of latex-based nanocomposite films

John Christopher Plummer, Riccardo Ruggerone

A waterborne latex-based technique, in which functionalized laponite is attached to PS and acrylic latex particles, is used to prepare films containing up to 50 wt% laponite. At high laponite contents this leads to a cellular arrangement of the laponite-ri ...

Three-dimensional morphometry of strained bovine periodontal ligament using synchrotron radiation-based tomography

John Botsis, Joël Cugnoni, Marzio Bergomi, Marco Stampanoni, Philipp Schneider

The periodontal ligament (PDL) is a highly vascularized soft connective tissue. Previous studies suggest that the viscous component of the mechanical response may be explained by the deformation-induced collapse and expansion of internal voids (i.e. chiefl ...

Analysis of the compaction phenomena due to the water injection in reservoirs with a three-phase geomechanical model

Lyesse Laloui, Mathieu Nuth

In the coastal regions, the land subsidence due to the industrial pumping of underground fluids such as methane is documented by the means of in situ surveys. The laboratory characterization of the gas bearing formations has also been published, which comp ...

Poinçonnement des planchers-dalles avec colonnes superposées fortement sollicitées

Roberto Guidotti

Flat slabs are commonly used in buildings due to their easiness of construction and economy. In order to keep these advantages, columns are usually not continuous through the slabs in multi-storey buildings. In these cases, the slabs are subjected to large ...

Multiaxial Yield and Fracture of Replicated Microcellular Aluminium

Etienne Combaz

This work addresses the behaviour of replicated microcellular pure aluminium under multiaxial stress states and in the presence of stress and strain localization sites. Processing of the foam was conducted in-house, using the replication process. The main ...

The role of the fluid phase in the viscous response of bovine periodontal ligament

John Botsis, Joël Cugnoni, Marzio Bergomi

The mechanical response of the periodontal ligament (PDL) is complex. This tissue responds as a hyperelastic solid when pulled in tension while demonstrating a viscous behavior under compression. This intricacy is reflected in the tissue's morphology, whic ...
