Effect of Stress on Water-Filled Inclusions in Viscoplastic Soils

Dani Or

The relationships between applied stress, deformation and internal pressure of water filled inclusions embedded in soft soils were studied to improve understanding of pore-scale mechanical behavior and towards development of methods for in situ measurement ...

Adhesively bonded lap joints of pultruded GFRP shapes

Till Vallée

The importance of Fibre Reinforced Polymers (FRPs) as a material used for civil engineering purposes has grown in the last decade. Especially the introduction of pultrusion at an industrial level as a way to produce big batches of FRP made it possible to o ...

Tragverhalten und Bemessung von Holz-Glas-Verbundträgern unter Berücksichtigung der Eigenspannungen im Glas

Klaus Kreher

The construction principles of "Timber-Glass-Composite-Girders" demand practical and theoretical research to ensure reliable designs. Toward this objective the mathematical description of load-bearing and the non-rigid bond is the subject of this work, i.e ...

Process-Induced Internal Stresses in Phenol-Formaldehyde Cellulose Composites

Phenol and melamine-formaldehyde (PF and MF) cellulose composites are being used extensively in the laminate industry. Despite their many advantages, flat panels produced from such materials have a tendency to warp immediately after processing as well as d ...

Transient moisture effects on wood creep

John Christopher Plummer

To gain insight into the physical nature of the coupling between mechanical stress and humidity variations, the behaviour of thin wood strips was studied using specially developed apparatus for creep/recovery and relaxation/blotting-out tests in a controll ...

Comportement mécanique des milieux granulaires sous sollicitations cycliques

Frédéric Mayoraz

The following work deals with the characterisation of the behaviour of road bases granular material, made of tunnel excavation material and loaded by passing vehicle axles. This granular media, don't correspond generally to the standards demanded for the c ...

Comportement mécanique d'un limon non saturé

Although the majority of soils are unsaturated, their mechanical behaviour is still not well defined. This dissertation presents first an experimental study of an unsaturated silt and then proposes an elasto-plastic constitutive law to model the behaviour ...
