Accelerating Electromigration Stress Analysis Using Low-Rank Balanced Truncation
(2022)Electromigration (EM) has become one of the most significant challenges considering longterm reliability in integrated circuit design. The problem is caused by the large current density in circuit interconnections. However, ... -
Analytical methodologies for buried pipeline design in geohazard areas
(2016)In geohazard areas, buried pipelines are subjected to permanent ground deformations, which constitute major threats for their structural safety. Geohazards include seismic fault movement, liquefaction-induced lateral ... -
Deformation vs. flow and wavelet-based models of gradient plasticity: Examples of axial symmetry
(2006)The modest goal of this article - the first in a series of three dedicated to Kirk Valanis - is to discuss and compare (in terms of their constitutive and variational formulation, boundary conditions and size-dependent ... -
The effect of stress triaxiality on the phase transformation in transformation induced plasticity steels: Experimental investigation and modelling the transformation kinetics
(2021)In situ multiaxial loading during neutron diffraction tests were undertaken on a low-alloyed Quenched and Partitioning (Q&P) Transformation Induced Plasticity (TRIP) Bainitic Ferrite (TBF) steel with dispersed austenite ... -
Effective-stress seismic analysis of a gravity multi-block quay wall
(2018)The seismic performance of an existing gravity quay wall consisting of concrete blocks is investigated using effective stress analysis. The study focuses on the effect of the uncertainty associated with the spatial variability ... -
