AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
FRP bridge decks offer several advantages compared with conventional concrete bridge decks, particularly their much lower weight, but also their resistance against corrosion as well as easier installation and maintenance. The poorly conceived methods avail ...
A new model considering fixed and interlocked cracks for the analysis of reinforced concrete (RC) cracked membrane elements is presented. The model can be regarded as an extension of the cracked membrane model proposed by Kaufmann and Marti. Its value lies ...
This research project experimentally and numerically investigates the growth and coalescence of pre-existing voids for a wide range of stress states in a ductile matrix with a special focus on shear dominated loading conditions and presents quantitative ki ...
The creep of a dislocation on its glide plane is essentially controlled by three different stress fields: the external applied stress, the internal stress field due to a multi-scale hierarchy of different obstacles (the structural defects acting on the dis ...
The determination of the thermal and athermal stress components using relaxation experiments along a stress-strain curve is critically evaluated. Short-term stress-relaxations are performed along the stress-strain curve of single crystals of Ge at 850 K, C ...
Structural stability issues in planar solid oxide fuel cells (SOFC) arise from the mismatch between the coefficients of thermal expansion (CTE) of the components. The stress state at operating temperature is the superposition of several contributions, whic ...
The Haasen plot (inverse activation area 1/Delta alpha vs. offset flow stress sigma-sigma(s)) for solute-strengthened alloys is usually assumed additive, 1/Delta alpha = 1/Delta alpha(s) + 1/Delta alpha(f), with 1/Delta alpha(f) similar to beta(sigma-sigma ...
The through-thickness performance of adhesive joints connecting pultruded FRP bridge decks and steel girders subjected to loading in the transverse bridge direction was investigated. Deck-to-girder adhesive joints can be assumed as being loaded by uplift f ...
The through-thickness performance of adhesive joints between pultruded FRP bridge decks and steel girders was investigated experimentally and numerically. Through- thickness tensile stresses occur due to uplift forces caused by the load-bearing behavior of ...
Aluminium-5 wt.% magnesium open cell foam produced by replication and tested in tension at 300, 350 or 450 degrees C creeps at rates between 10(-3) and 10(-8) s(-1). The behaviour of the foam matches that of the alloy from which it is made: three-power law ...
