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…

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…

A tensorial thermodynamic framework to account for the γ ' rafting in nickel-based single crystal superalloys

A new model is developed in order to account for the effect of microstructural degradation (i.e. precipitate-directional-coarsening) on the viscoplastic behavior of single crystal superalloys under high temperature exposure. Microstructural changes…
