Non-linear viscoelasticity analysis for CTAB/NaSal wormlike micellar solution in large amplitude oscillatory shear

open access: yesNihon Kikai Gakkai ronbunshu, 2015
Non-linear viscoelastic behavior of a wormlike micellar solution of cetyltrimethylammonium bromide (CTAB) and sodium salicylate (NaSal) in the large amplitude oscillatory shear (LAOS) is examined. A transient response of the shear stress after applying a

Advanced Electron Microscopy and Microcomputed Tomography Analysis of Single‐Crystal Ni‐Base Superalloys After Short‐Term Multiaxial Creep

open access: yesAdvanced Engineering Materials, EarlyView.
This work studies the anisotropic behavior of circular notched tensile specimens of Ni‐base superalloy single crystals during high‐temperature tensile creep along [001], [110], and [111]. Correlative scale‐bridging imaging of specimens reveals early rupture along [110] because 1) plastic deformation proceeds faster at notch center; 2) more (brittle ...

Analysis of influence of initial shear stress on undrained instability characteristics of construction waste soil

open access: yesYantu gongcheng xuebao
The stress distribution and variation inside loosely deposited construction waste soil are highly complex. In particular, the continuous filling process alters the initial shear stress, which may significantly change the instability behavior of the waste

Wall shear stress revisited

open access: yesArtery Research, 2009
In vivo measurements of wall shear stress (WSS), a determinant of endothelial cell function and gene expression, have shown that theoretical assumptions regarding WSS in the arterial system and its calculation are invalid. In humans mean WSS varies along

Design and Analysis of Compression–Torsion Coupling Metamaterials Using the Golden Section Method

open access: yesAdvanced Engineering Materials, EarlyView.
A novel compression–torsion metamaterial is engineered using inclined rods and symmetry breaking. To optimize its torsional performance, the golden section method is employed. The mechanical response of the metamaterial is validated through both numerical analysis and experimental validation.

Influence of Scan Strategies in Electron Beam Powder Bed Fusion on Solidification, Microstructure, and High‐Temperature Compressive Properties of γ′‐Strengthened Inconel 738LC

open access: yesAdvanced Engineering Materials, EarlyView.
Experiments and thermophysical simulations were conducted to investigate the electron beam powder bed fusion electron beam (PBF‐EB/M) process for the γ′‐strengthened nickel‐based superalloy Inconel 738LC. The results demonstrate the impact of process‐induced microstructural variations on high‐temperature mechanical behavior, providing a basis for ...

Shear Capacity Model of Prefabricated Shear-Keyed Tooth Joints Under Confining Stress

open access: yesBuildings
Shear-keyed tooth joints (SKTJs) are commonly used in prefabricated buildings, including wind turbine foundations, to connect prestressed modules. Due to the significant loss of prestress in precast wind turbine foundations, slip failure is more likely ...

External and Internal Cracking Caused by Heat Treatment in Laser Powder Bed Fusion‐Fabricated Inconel 738LC Components

open access: yesAdvanced Engineering Materials, EarlyView.
Manufacturing problems such as heat treatment‐induced cracking hinder the widespread application of the laser powder bed fusion (LPBF) process to superalloys. In this study, cracks in the LPBF components of Inconel 738LC superalloy are characterized after heat treatment at various temperature ranges, revealing two distinct cracking behaviors.
