Title: Microscale shear specimens for evaluating the shear deformation in single-crystal and nanocrystalline Cu and at Cu–Si interfaces

Abstract

Microscale testing has enjoyed significant developments, with the majority of testing focused on tensile/compression type tests and little focus on shear testing. With the recent advances in macroscale shear testing, we developed a novel shear structure for evaluating shear properties of bulk materials and films at the microscale. The shear response in single-crystal copper oriented along the [111] direction was found to have a yield strength of ~180 MPa. Nanocrystalline copper specimens with different orientations showed sensitivity to the film texture with a shear yield strength nearly three times that of single-crystal copper. Shear specimens were fabricated with Cu film–Si substrate interface near the middle of the shear region and compressed to fracture. Here, the shear response showed a mixed behavior of the stiff Si substrate and softer nanocrystalline film and failed in a brittle manner, indicating a response unique to the interface.

Benchmarking Microscale Ductility Measurements (Final Report of the Project DE-NE0008799)

Technical Report Kingstedt, Owen T. ; Spear, Ashley D. ; Chang, Jiyoung ; ...

Conventional macroscale experimentation is generally considered to be straightforward with few limitations. Conversely, micro/nanoscale experimentation presents numerous challenges in loading device design, sample preparation and handling, as well as accurate understanding of grain size and local texture effects on recorded measurements. Despite these challenges, nanopillar compression, MEMs based micro-tension, and nanoindentation approaches have been able to provide fundamental contributions to the understanding of material behavior at small lengthscales. However, the overarching shortcoming of these micro/nanoscale experimentation approaches, is the inability to directly translate measurements evaluated at the nm and µm length scales (e.g., hardness) to macroscale tensile material behavior (i.e.,more »« less

Intermetallic particle heterogeneity controls shear localization in high-strength nanostructured Al alloys

Journal Article Lei, Tianjiao ; Hessong, Esther C. ; Shin, Jungho ; ... - Acta Materialia

The mechanical behavior of two nanocrystalline Al alloys, Al-Mg-Y and Al-Fe-Y, is investigated with in-situ micropillar compression testing. Both alloys were strengthened by a hierarchical microstructure including grain boundary segregation, nanometer-thick amorphous complexions, carbide nanorod precipitates with sizes of a few nanometers, and submicron-scale intermetallic particles. The maximum yield strength of the Al-Mg-Y system is measured to be 950 MPa, exceeding that of the Al-Fe-Y system (680 MPa), primarily due to a combination of more carbide nanorods and more amorphous complexions. Both alloys exhibited yield strengths much higher than those of commercial Al alloys, and therefore have great potential formore »« less

Interface shear properties and toughness of NiAl/Mo laminates

Journal Article Pickard, S M ; Zhang, H ; Ghosh, A K - Acta Materialia

Mechanical properties at the interface between NiAl intermetallic and Mo ductile phase in sandwich laminates have been studied under a variety of stress states involving primarily shear. A shear-compression test for laminates of NiAl/Mo/NiAl has been used in which a double-notched specimen with cut-through metal interlayer is loaded to failure in compression. Because of the large elastic mismatch between NiAl and Mo, a primarily shear loading generates a significant amount of normal stress in this test. Interface shear response and toughness obtained using this technique are compared for NiAl/Mo laminates with interfacial segregant, Cr, Re and C layers fabricated bymore »« less

Active- and transfer-learning applied to microscale-macroscale coupling to simulate viscoelastic flows

Journal Article Zhao, Lifei ; Li, Zhen ; Wang, Zhicheng ; ... - Journal of Computational Physics

Active- and transfer-learning are applied to microscale dynamics of polymer flows for the multiscale discovery of effective constitutive approximations required in viscoelastic flow simulation. The result is macroscopic rheology directly connected to a microstructural model. Micro and macroscale simulations are adaptively coupled by means of Gaussian process regression (GPR) to run the expensive microscale computations only as necessary. This multiscale method is demonstrated with flows of a polymer solution as a model system. At the microscale level dissipative particle dynamics (DPD) is employed to model the fluid as a suspension of bead-spring micro-structures subjected to steady shear flow. The resultsmore »« less

Interfacial sensitivity of transverse and shear tests for CF/EP composites using flat and tubular specimens

Conference Hoecker, F ; Ehlers, C ; Karger-Kocsis, J

The aim of this study was to assess the interface-relevance (IR), i.e. interface-dependent mechanical parameters in composites with a well-defined variation in the fiber/matrix adhesion. Transverse and shear properties of flat and tubular specimens were determined in different mechanical tests. A further scope of this study was to check how the interface (fiber/matrix bond quality) affects the mechanical response using unidirectional (UD) flat composite laminates and hoop-wound tubular specimens. In detail, transverse tensile, three-point bending, short beam shear (SBS), transverse Iosipescu and direct shear tests were performed on carbon fiber (CF)/epoxy (EP) matrix UD composite plates. In all the aforementionedmore »« less
