Consideration and Propagation of Ground Motion Selection Epistemic Uncertainties to Seismic Performance Metrics

This paper investigates various approaches to propagate the effect of epistemic uncertainty in seismic hazard and ground motion selection to seismic performance metrics. Specifically, three approaches with different levels of rigor are presented for…

Influential factors in volume change measurements for cementitious materials at early ages and in Isothermal conditions

Early age deformations, when restrained, lead to an increase of cracking risk of the material, especially in the case of high strength materials to which we apply modern high energy mixing techniques which accelerate initial hydration rate. The…

Toward an integrated seismic risk assessment for nuclear safety improving current French methodologies through the SINAPS@ research project

The Tohoku earthquake and associated tsunami in March 2011 caused a severe nuclear accident at the Fukushima Daiichi Nuclear Power Plant, where level 7 (International Atomic Energy Agency (IAEA) – INES scale) meltdown at three reactors occurred. The…

Multiscale GFEM with superposition of crack enrichment functions driven by finite fracture mechanics: Theory, first computation and open problems

This work presents a direct extension of the multiscale GFEM (MS-GFEM) where damage and fracture mechanisms are now taken into account. Using a pattern-based description of the microscale, the construction of the model falls into two main parts: the…

On wave based weak Trefftz discontinuous Galerkin approach for medium-frequency heterogeneous Helmholtz problem

Medium frequency heterogeneous Helmholtz problem gives rise to severe numerical challenge to Finite Element Method (FEM). An extended Variational Theory of Complex Rays (VTCR) is developed for solving this problem. Since VTCR is kind of Trefftz…

γ′-Rafting mechanisms under complex mechanical stress state in Ni-based single crystalline superalloys

The morphological evolution of the γ′ precipitates has been studied in a second generation nickel-based single crystal superalloy during isothermal creep straining at 1093 °C under multiaxial stress state. For this purpose, a specific V-shaped…
