Shear strength of compacted sandstone-mudstone mixtures based on field large-scale direct shear tests

Yantu gongcheng xuebao
The tests on the shear strength parameters of the compacted sandstone-mudstone mixtures as well as the analyses of their influencing factors are meaningful to guide the stability evaluation, design and construction of ultra-high fill slopes.

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

Advanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

Experimental Characterization and Constitutive Modeling of the Effect of Prior Inelastic Strain on the Viscoplastic Behavior of AD730 at 700 °C

Advanced Engineering Materials, EarlyView.
This study shows that superalloys used in aircraft engine disks become much more prone to deformation at high temperatures if they have been strained during manufacturing. This effect increases with the level of prior strain but eventually reaches a limit.

Factors residual strength of Luochuan loess

Yantu gongcheng xuebao, 2017
In the loess regions loess landslide is one of the major geological disasters. Every year it results in a large number of casualties and destructions. It is found that the average shear stress on the sliding surface of these landslides is much smaller ...

Precipitation Simulations of the O‐Phase in Ti2AlNb Alloys Processed by Laser Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Simulated and experimental evolution of the O‐phase volume fraction during postprocessing of a Ti‐21Al‐25Nb (at.%) alloy processed by laser powder bed fusion. With results of sensitivity to input parameters from a thorough and quantified analysis, the interfacial energy matrix/precipitate is the most relevant input parameter for the simulation of the O‐

Strength characteristics of dump materials derived from laboratory and in-situ direct shear tests and their effects on slope stability

Meitan xuebao
The mechanical properties and scale effects of dump materials are critical factors affecting the reliability of slope stability analysis in open-pit coal mines. To address the discrepancy between laboratory test materials and in-situ raw materials, which

Effect Of Polypropylene On Shear Strength Parameters

, 2018
In this research the shear strength parameter of Highly cohesive soil is discussed. A Comparison of shear strength parameters and ultimate bearing capacity by direct shear test at various water content is calculated. Most of the engineering design methods and parameters of structure on soil have been developed for ideal soil, such as expansive clay ...

Modeling Dislocation Cutting of γ′ Precipitates in Ni‐Base Superalloys: Linking Atomistic and Dislocation Dynamics Simulations

Advanced Engineering Materials, EarlyView.
Dislocation cutting of γ′ precipitates in Ni‐based superalloys is investigated by linking atomistic simulations with discrete dislocation dynamics. The critical cutting stress is shown to be governed by the antiphase boundary energy, while line tension effects promote edge‐preferred cutting.

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

Advanced 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 ...
