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.
Background: Total Ankle Replacement (TAR) o_ers the advantage of preserving ankle joint motion compared with ankle arthrodesis. However, compared to hip or knee arthroplasty, TAR is a less successful procedure when considering the relatively low implants s ...
Stress relief treatment is often required prior to sawing aluminum DC cast products in order to prevent crack formation and significant safety concerns due to the presence of high residual stresses generated during casting. Numerical models have been devel ...

Stress wave attenuation across fractured rock masses is a great concern of underground structure safety. This paper presents an analytical study on wave attenuation across parallel fractures at arbitrary incidence angles, where multiple reflections occurri ...
Reversed shoulder arthroplasty (RSA) is recommended in case of severe muscle deficiency, along with important joint wear. Although having a correct placement of the prosthesis after the operation and a recovery of the mobility, several cases of scapula fra ...
A critical aspect in the design of tubular bridges is the fatigue performance of the structural joints. The estimation of a fatigue crack life using the linear elastic fracture mechanics (LEFM) theory involves the calculation of stress intensity factors (S ...
Due to the difficulties of fracture mechanics in dealing with multicrack problems, the continuum-based numerical methods always encounter mathematical problems when modeling rock fragmentation, so the alternative discontinuum-based numerical approaches are ...
The SELFRAC project aimed to study the fractures within the Excavation Damaged Zone (EDZ) around galleries in the Boom clay and Opalinus clay formations and their possible sealing/healing with time. Tests carried out at LMR-EPFL aimed at quantifying on the ...
In this study, a two-dimensional plane strain finite element model is used for the prediction of mechanical and hydraulic behaviour of pre-stressed concrete-lined pressure tunnels. Results obtained from numerical models are presented and compared with the ...
The purpose of this paper is to present a detailed experimental procedure for the quantitative determination of initiation fracture toughness and full-field strain measurement of rock material under dynamic loads. Notched semi-circular bending tests were c ...
A new phenomenological fatigue crack growth formulation for the modeling and the prediction of the Model fatigue behavior of adhesively-bonded pultruded glass fiber-reinforced polymer double cantilever beam joints under different R-ratios is introduced. Th ...
