Unravelling the mechanisms underlying crack initiation in additively manufactured steel
KenHee Ryou, Yaozhong Zhang, James A. D. Ball +7
Metal additive manufacturing (AM) is increasingly adopted for safety-critical applications across the biomedical, aerospace, and energy sectors. However, many AM alloys exhibit sub…
Theoretical Analysis of Topotomography Using Small Intragranular Strain Approximations
Zheheng Liu, Nicola Vigano, Henry Proudhon +1
Topo-Tomography (TT) is a synchrotron-based X-ray diffraction imaging technique used to characterize grain shape and crystal orientation in polycrystalline samples. This work aims…
Observation of Bulk Plasticity in a Polycrystalline Titanium Alloy by Diffraction Contrast Tomography and Topotomography
J. C. Stinville, W. Ludwig, P. G. Callahan +4
The mechanical properties of polycrystalline metals are governed by the interaction of defects that are generated by deformation within the 3D microstructure. In materials that def…
A modular U-Net for automated segmentation of X-ray tomography images in composite materials
João P C Bertoldo, Etienne Decencière, David Ryckelynck +1
X-ray Computed Tomography (XCT) techniques have evolved to a point that high-resolution data can be acquired so fast that classic segmentation methods are prohibitively cumbersome,…
Multiscale modeling of the elastic behavior of architectured and nanostructured Cu-Nb composite wires
T. Gu, O. Castelnau, S. Forest +4
Nanostructured and architectured copper niobium composite wires are excellent candidates for the generation of intense pulsed magnetic fields (>90T) as they combine both high stren…
Finite element analysis of fretting crack propagation
Henry Proudhon, Stéphanie Basseville
In this work, the finite elements method (FEM) is used to analyse the growth of fretting cracks. FEM can be favourably used to extract the stress intensity factors in mixed mode, a…
