Additively manufactured stretchable zipping electrostatic actuators
The use of soft and stretchable materials allows the development of adaptive robotic systems and human-machine interfaces that are more natural and comfortable to interact with. One of the application fields that benefits the most from these compliant mate ...
EPFL2024Model uncertainties in action effects and load bearing capacity calculation in statically indeterminate reinforced concrete structures
Aurelio Muttoni, Alain Nussbaumer, Xhemsi Malja
For the dimensioning and assessment of structures, it is common practice to compare action effects with sectional resistances. Extensive studies have been performed to quantify the model uncertainty on the resistance side. However, for statically indetermi ...
Ernst & Sohn2024Development of a scintillator based fast-ion loss detector for the Wendelstein 7-X stellarator
A new scintillator based fast -ion loss detector (FILD) system has been designed for the Wendelstein 7-X (W7X) stellarator. The mechanical design of the system is presented here along with engineering analyses of the system. This includes an assessment of ...
2024Experimental investigation of dowel action in reinforcing bars using refined measurements
Aurelio Muttoni, Marko Pejatovic
In typical reinforced concrete design, reinforcement is designed to carry axial forces, but it can also resist transversal forces by dowel action. This is usually neglected for simplicity's sake in the design phase, but it can be accounted for either expli ...
Ernst & Sohn2024Mechanically induced correlated errors on superconducting qubits with relaxation times exceeding 0.4 ms
Tobias Kippenberg, Amir Youssefi, Marco Scigliuzzo, Mahdi Chegnizadeh, Shingo Kono, Xuxin Wang
Superconducting qubits are among the most advanced candidates for achieving fault-tolerant quantum computing. Despite recent significant advancements in the qubit lifetimes, the origin of the loss mechanism for state-of-the-art qubits is still subject to i ...
Nature Portfolio2024Leibniz en Créateur. Un regard matériel sur sa machine à calculer
Simon François Dumas Primbault
Between 1671 and 1716, the German mathematician Gottfried Wilhelm Leibniz attempted to design a reckoning machine. Working closely with the Parisian clockmaker Monsieur Ollivier, Leibniz eventually failed at producing a working prototype. After the redisco ...
2022Pde-Constrained Optimization For Nuclear Mechanics
We propose an image based PDE-constrained optimisation framework to compute the dynamical quantities of a cell nucleus undergoing deformation. It allows retrieving the displacement, strain and stress at each pixel of the nuclear domain, as well as the trac ...
IEEE2022Principle and Analysis of Radial-Force-Based Swirling Actuator for Low-Speed High-Torque Applications
This article proposes a swirling actuator that uses the electromagnetic radial force and mechanical gears to generate rotational torque. The proposed actuator generates a rotating radial force between an inner stator and a swirler. The gears on the swirler ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Anchorage of shear reinforcement in beams and slabs
Aurelio Muttoni, Qianhui Yu, Miguel Fernández Ruiz, Frédéric Monney
Anchorage of shear reinforcement, such as links or stirrups, can be performed by providing hooks, bends or heads at their ends, by welding transverse reinforcement or by closing open stirrups with pins. Hooks and bends, also used to enhance the anchorage o ...
ELSEVIER SCI LTD2022Experimental investigation of dowel action using advanced measurement techniques
Aurelio Muttoni, Marko Pejatovic
Existing shear-cracked structures need to be reliably verified in order to avoid redundant interventions. Code provisions often raise shear safety and/or fatigue life concerns of the reinforcement subjected to stress concentrations due to cyclic dowel acti ...
