STEEL-3dPointClouds: dataset supporting quantification of residual life and reusability of steel beam-columns

Tianyu Gu, Dimitrios Lignos, Guillaume Romain Obozinski, Isinsu Katircioglu, Nenad Bijelic

This paper presents STEEL-3dPointClouds, a dataset of deformed steel beam-columns obtained using high-fidelity physics-based numerical simulations. These simulations trace the inelastic deformations of hot-rolled wide-flange steel beam-columns under differ ...

Solving a class of infinite-dimensional tensor eigenvalue problems by translational invariant tensor ring approximations

Daniel Kressner

We examine a method for solving an infinite-dimensional tensor eigenvalue problem (Formula presented.), where the infinite-dimensional symmetric matrix (Formula presented.) exhibits a translational invariant structure. We provide a formulation of this type ...

A variational approach to deriving Hamiltonian functions under non-holonomic constraints — the case of the Gaussian thermostats

Deepak Somani

For systems under holonomic constraints, H can be derived from the principle of least action (PLA) formulated in terms of a suitable set of generalized coordinates. In molecular dynamics (MD) simulations, where the system temperature often prescribes a non ...

TV-based spline reconstruction with Fourier measurements: Uniqueness and convergence of grid-based methods

Julien René Fageot, Thomas Jean Debarre, Quentin Alain Denoyelle

We study the problem of recovering piecewise-polynomial periodic functions from their low-frequency information. This means that we only have access to possibly corrupted versions of the Fourier samples of the ground truth up to a maximum cutoff frequency ...

Model uncertainties and partial safety factors of strain-based approaches for structural concrete: Example of punching shear

Aurelio Muttoni, Qianhui Yu, João Tiago Ramos Bernardo de Santa Rita Simões

The development of mechanical models relating the state of strains and the resistance of reinforced concrete structures has become a trend in the last decades. These types of models are referred to as strain-based approaches. Since strain-based approaches ...

Reduced order modeling for parametrized generalized Newtonian fluid flows

Ricardo Reyes Sotomayor

Non-Newtonian fluids are present in most manufacturing industry processes. Computa-tional models used to describe the rheological behavior of such materials can be costly due to the non-linear behavior of the viscosity. This work presents a parametrized pr ...

Seismic demands of steel moment resisting frames with inelastic beam-to-column web panel zones

Dimitrios Lignos, Andronikos Skiadopoulos

This paper intends to provide quantitative seismic response characteristics of steel moment resisting frames (MRFs) with inelastic beam-to-column panel zone joints. Two modeling approaches are proposed for this purpose along with a methodology to consider ...

Coupling of non-conforming trimmed isogeometric Kirchhoff-Love shells via a projected super-penalty approach

Annalisa Buffa, Luca Coradello

Penalty methods have proven to be particularly effective for achieving the required C-1-continuity in the context of multi patch isogeometric Kirchhoff-Love shells. Due to their conceptual simplicity, these algorithms are readily applicable to the displace ...

Discrete shedding of secondary vortices along a modified Kaden spiral

Karen Ann J Mulleners, Diego Francescangeli

When an object is accelerated in a fluid, a primary vortex is formed through the roll-up of a shear layer. This primary vortex does not grow indefinitely and will reach a limiting size and strength. Additional vorticity beyond the critical limit will end u ...

On the modelling of the transition between contact-line and microlayer evaporation regimes in nucleate boiling

Lubomír Bures

Formation of a microlayer in nucleate boiling results in substantial changes to the heat-transfer dynamics of the process, and establishing a criterion to distinguish between the microlayer and contact-line regimes encountered is necessary to obtain a quan ...

Experimental facility for reduced scale model testing of hydraulic machines hybridized with a battery energy storage system

Mario Paolone, Sidi-Rachid Cherkaoui, Elena Vagnoni, Francesco Gerini, Martin Seydoux

With a continuously growing share of non-dispatchable renewable energy sources in the power mix, flexibility in hydropower provision is becoming fundamental. The major role played by hydropower in frequency regulation in the last years has underlined the p ...
