Controlling superconductivity of CeIrIn5 microstructures by substrate selection

Philip Johannes Walter Moll, Maja Deborah Bachmann, Matthias Carsten Putzke, Chunyu Guo, Maarten Ruud van Delft, Joshua Alan Wolfe Straquadine

Superconductor/metal interfaces are usually fabricated in heterostructures that join these dissimilar materials. A conceptually different approach has recently exploited the strain sensitivity of heavy-fermion superconductors, selectively transforming regi ...

Data-Driven C-Refinement A proof-of-concept

Jean-François Molinari, Antonio Joaquin Garcia Suarez, Sacha Zenon Wattel

This poster was presented at the IUTAM Symposium on Data-driven mechanics, taking place in Paris, France in Octoboer 2022. It shows a proof-of-concept for a new application of Data-Driven Computational Mechanics (DDCM): using it as a new type of adaptive r ...

Scaling Description of Creep Flow in Amorphous Solids

Matthieu Wyart, Thomas Willem Jan de Geus, Wencheng Ji, Marko Popovic

Amorphous solids such as coffee foam, toothpaste, or mayonnaise display a transient creep flow when a stress E is suddenly imposed. The associated strain rate is commonly found to decay in time as gamma_ -t-nu, followed either by arrest or by a sudden flui ...

Order parameters for antiferromagnetic structures: A first-principles study of iridium manganese

Anirudh Raju Natarajan

We use density-functional theory to study the ordered states of iridium manganese, demonstrating a simple but powerful method for describing magnetic structures and the transitions among them. As an illustrative example, the coupling of magnetism and cryst ...

Bragg edge tomography characterization of additively manufactured 316L steel

Roland Logé, Christian Leinenbach, Markus Strobl, Nikola Kalentics, Efthymios Polatidis

In this work we perform a neutron Bragg edge tomography of stainless steel 316L additive manufacturing samples, one as built via standard laser powder bed fusion, and one using the novel three-dimensional (3D) laser shock peening technique. First, we consi ...

A numerical approach to characterize the viscoelastic behaviour of fibre beds and to evaluate the influence of strain deviations on viscoelastic parameter extraction

Véronique Michaud, Vincent Werlen, Christian Rytka

The development of a robust material model able to accurately describe fibre bed compaction at different strain and strain rates is highly desirable because it is essential for the simulation of many composite manufacturing processes. In this study, we inv ...

Constitutive Modeling of Structural Steels: Nonlinear Isotropic/Kinematic Hardening Material Model and Its Calibration

Dimitrios Lignos, Albano António De Abreu E Presa De Castro E Sousa

Numerical models of structural components that deteriorate primarily due to geometric instabilities under multiaxis cyclic loading are sensitive to both the assumed geometric imperfections and the nonlinear material model assumptions. Therefore, the accura ...

Discussion on "Experimental Deformation of Opalinus Clay at Elevated Temperature and Pressure Conditions: Mechanical Properties and the Influence of Rock Fabric" of Schuster, V., Rybacki, E., Bonnelye, A., Herrmann, J., Schleicher, AM, Dresen, G.

Lyesse Laloui, Alessio Ferrari, Eleonora Crisci

The testing procedure and results on saturated samples of Opalinus Clay in the work of Schuster et al. (Rock Mech Rock Eng https://doi.org/10.1007/ s00603-021-02474-3, 2021) were conducted and presented using strain rates two to four orders of magnitudes h ...

Numerical modeling of two-dimensional delamination growth in composite laminates with in-plane isotropy

Thomas Keller, Anastasios Vassilopoulos, Congzhe Wang

The two-dimensional (2D) delamination growth in fiber-reinforced polymer (FRP) laminates with in-plane isotropy under Mode I loading condition was numerically investigated using finite element analyses. Two sizes of plate models were developed, focusing on ...

Novel insights into the design of stretchable electrical systems

Fabien Sorin, Pierre-Luc Eloi Piveteau, Louis Marie Philippe Martin-Monier

Soft electronics have recently gathered considerable interest because of their biomechanical compatibility. An important feature of deformable conductors is their electrical response to strain. While development of stretchable materials with high gauge fac ...
