Strain-based analysis on the influence of local undercut geometry on fatigue crack initiation life
Alain Nussbaumer, Heikki Tapani Remes, Abinab Niraula
The local undercut defects at the weld toe provide a potential initiation site for fatigue cracks and significantly impact the structure's fatigue strength. The influence of continuous undercut depth on fatigue performance is widely studied, but the resear ...
2024Multimaterial Volumetric Printing of Silica-Based Glasses
Christophe Moser, Paul Delrot, Jorge Andres Madrid Wolff, Damien Claude-Marie Loterie, Antoine Vincent Boniface, Roberto Arturo Emma
Silicate glasses have played a major role as structural and functional materials in human civilization since ancient Egypt. Despite their widespread use and importance in modern society, silica glasses with complex geometries are only fabricated in automat ...
Hoboken2024T-5 configurations and hyperbolic systems
Carl Johan Peter Johansson, Riccardo Tione
In this paper, we study the rank-one convex hull of a differential inclusion associated to entropy solutions of a hyperbolic system of conservation laws. This was introduced in [B. Kirchheim, S. Muller and V. S(sic)ver & aacute;k, Studying Nonlinear PDE by ...
WORLD SCIENTIFIC PUBL CO PTE LTD2023Comparing the Buckling Strength of Spherical Shells With Dimpled Versus Bumpy Defects
Pedro Miguel Nunes Pereira de Almeida Reis, Fani Derveni, Arefeh Abbasi
We investigate the effect of defect geometry in dictating the sensitivity of the critical buckling conditions of spherical shells under external pressure loading. Specifically, we perform a comparative study between shells containing dimpled (inward) versu ...
ASME2023Reduced order modelling of nonaffine problems on parameterized NURBS multipatch geometries
Annalisa Buffa, Pablo Antolin Sanchez, Margarita Chasapi
This contribution explores the combined capabilities of reduced basis methods and IsoGeometric Analysis (IGA) in the context of parameterized partial differential equations. The introduction of IGA enables a unified simulation framework based on a single g ...
2022Stabilized isogeometric discretizations on trimmed and union geometries, and weak imposition of the boundary conditions for the Darcy flow
Modern manufacturing engineering is based on a ``design-through-analysis'' workflow. According to this paradigm, a prototype is first designed with Computer-aided-design (CAD) software and then finalized by simulating its physical behavior, which usually i ...
EPFL2022Conjugate heat transfer in isolated granular clusters with interstitial fluid using lattice Boltzmann method
The conjugate heat transfer in mixtures of a fluid and single granular clusters is studied in this paper using a novel lattice Boltzmann method (LBM) programmed for parallel computation on the graphics processing unit (GPU). The LBM is validated for heat c ...
PERGAMON-ELSEVIER SCIENCE LTD2022An unrefinement algorithm for planar THB-spline parameterizations
Unrefinement is a tool that allows to perform faster numerical simulations by controlling the level of precision in the specified area. We introduce an algorithm that creates a coarser geometry from an initial regular geometry, which is represented with re ...
ELSEVIER2022How Leibniz read Pascal’s Geometry: The Practice of Reading as Hybrid Hermeneutics in the Materiality of Leibniz’s Pascaliana
Simon François Dumas Primbault
Between 1675 and 1676, while in Paris, Gottfried Wilhelm Leibniz (1646–1716) got privileged access to some geometric manuscripts from late Blaise Pascal’s hand. Although said manuscripts are not extant, Leibniz’s reading notes were preserved, together with ...
2022GeoNeRF: Generalizing NeRF with Geometry Priors
We present GeoNeRF, a generalizable photorealistic novel view synthesis method based on neural radiance fields. Our approach consists of two main stages: a geometry reasoner and a renderer. To render a novel view, the geometry reasoner first constructs cas ...
