Modeling friction and wear using an adaptive discrete-continuum coupling
Manon Eugénie Voisin--Leprince
When two objects slide against each other, wear and friction occur at their interface. The accumulation of wear forms what is commonly referred to as a ``third-body''. Understanding third-body evolution has significant applications in industry, where contr ...
EPFL2024Room-temperature strength of the interfacial bond between silica inclusions and iron
Andreas Mortensen, David Hernandez Escobar, Alejandra Inés Slagter, Sergio Perosanz Amarillo
The strength of the interface between iron (Fe) and individual spherical silica (SiO2) inclusions of 5 +/- 1 mu m diameter is measured by means of in-situ micro-cantilever bending tests conducted under displacement control within a scanning electron micros ...
Oxford2023C-shells: Deployable Gridshells with Curved Beams
Mark Pauly, Francis Julian Panetta, Seiichi Eduardo Suzuki Erazo, Quentin Christian Becker, Yingying Ren, Davide Pellis
We introduce a computational pipeline for simulating and designing C-shells, a new class of planar-to-spatial deployable linkage structures. A C-shell is composed of curved flexible beams connected at rotational joints that can be assembled in a stress-fre ...
2023Laser powder bed fusion of Fe-based shape memory alloys for novel structural metamaterials and "smart" structures
Laser powder bed fusion (LPBF) is a powder-based additive manufacturing (AM) technique, which shows great potential in the production of complex-shaped parts with unprecedented design freedom. In addition, it allows for an active manipulation of the micros ...
EPFL2023Umbrella Meshes: Elastic Mechanisms for Freeform Shape Deployment
Mark Pauly, Florin Isvoranu, Uday Kusupati, Tian Chen, Yingying Ren, Davide Pellis
We present a computational inverse design framework for a new class of volumetric deployable structures that have compact rest states and deploy into bending-active 3D target surfaces. Umbrella meshes consist of elastic beams, rigid plates, and hinge joint ...
2022Mesh d-refinement: a data-based computational framework to account for complex material response
Jean-François Molinari, Antonio Joaquin Garcia Suarez, Sacha Zenon Wattel
Model-free data-driven computational mechanics (DDCM) is a new paradigm for simulations in solid mechanics. The modeling step associated to the definition of a material constitutive law is circumvented through the introduction of an abstract phase space in ...
2022Active load cell with positive, negative and zero stiffness operating modes for micronewton range contact force monitoring in electrical probing
Simon Nessim Henein, Charles Baur, Hubert Pierre-Marie Benoît Schneegans, Michal Stanislaw Smreczak
This article describes a novel method for applying a contact force in the range of 1 to 100 μN with pointed probe on a microscale sample in order to perform ohmic electrical measurements. The solution is based on the new TIVOT active load cell combining th ...
2022Computational Inverse Design of Surface-based Inflatables
Mark Pauly, Florin Isvoranu, Tian Chen
We present a computational inverse design method for a new class of surface-based inflatable structure. Our deployable structures are fabricated by fusing together two layers of inextensible sheet material along carefully selected curves. The fusing curves ...
ASSOC COMPUTING MACHINERY2021Viscoelastic surface electrode arrays to interface with viscoelastic tissues
Stéphanie Lacour, Alix Esther Anne Trouillet, Nicolas Vachicouras, Florian Dylan Fallegger, Christina Myra Tringides
Bioelectronic interfacing with living tissues should match the biomechanical properties of biological materials to reduce damage to the tissues. Here, the authors present a fully viscoelastic microelectrode array composed of an alginate matrix and carbon-b ...
NATURE RESEARCH2021Probing the buckling of pressurized spherical shells
Pedro Miguel Nunes Pereira de Almeida Reis, Dong Yan, Arefeh Abbasi
The prediction of the critical buckling conditions of shell structures is plagued by imperfection sensitivity. Non-destructive testing through point-load probing has been recently proposed to map the stability landscape of cylindrical shells. However, the ...
