Influence of biaxial stress on magnetostriction—Experiments and modeling

The paper deals with the influence of biaxial stress on the magnetic and magnetostriction behavior of a low carbon steel used for structural pieces in the car industry. Material, specimen, measurement setup and protocol are presented. Anhysteretic…

A mixed stress-strain driven computational homogenization of spiral strands

Spiral strands subjected to tensile force and bending loading display a nonlinear dissipative behavior due to frictional interactions between their elementary wires. This study aims to provide an efficient method, based on a computational…

Boundary condition effect on the evaluation of stress triaxiality fields

A general framework is presented for evaluating stress triaxiality fields using five different configurations of Dirichlet boundary conditions. The latter ones were measured via stereocorrelation for a simple shear test on a thin sample where…

Hierarchically guided in situ nanolaminography for the visualisation of damage nucleation in alloy sheets

Hierarchical guidance is developed for three-dimensional (3D) nanoscale X-ray imaging, enabling identification, refinement, and tracking of regions of interest (ROIs) within specimens considerably exceeding the field of view. This opens up new…

Representation Theory

On the isotropy stratification of a real representation of a compact Lie group

The aim of the present paper is to provide a comprehensive introduction to some algebraic and geometric aspects of real representations of compact Lie groups, as well as some results concerning isotropy strata and restriction of invariants.

Automated conformal mesh generation chain for woven composites based on CT-scan images with low contrasts

A novel approach to generate conformal meshes of woven composites at the mesoscopic scale from low-contrast CT-scan images with reconstruction artifacts is presented. The segmentation of the CT-scans relies on texture analysis of the tomography to…

The analysis of internal stresses on a welded joint in Grade 91 steel under creep test loading: Synchrotron X-ray diffraction measurements and modelling

The analysis and understanding of creep damage of Grade 91 steel welded joints is an important topic in the energy industry. Creep tests on welded joints were carried out at 600 • C, 100 MPa and then interrupted at 0%, 10%, 30%, 50%, 80% of the…

A simple and efficient process for the synthesis of 2D carbon nitrides and related materials

This manuscript describes a new process for the synthesis of very high quality 2D Covalent Organic Frameworks (COFs), such a C2N and CN carbon nitrides. The structure/quality of these materials is demonstrated by extensive cross-characterisations at…
