Calorimetric consequences of thermal softening in Johnson–Cook’s model [PDF]

, 2013
At high loading rates, the development of adiabatic shear bands in metals is conventionally attributed to the strong interactions induced by viscoplastic dissipation within the bands and thermal softening effects.

Experimental study on pull-out resistance of plate anchors at different buried depths

Yantu gongcheng xuebao, 2023
The plate anchor is widely used because of its good bearing characteristics, but the bearing characteristics are different at different buried depths. In order to study the tensile bearing characteristics of the anchor plate, a self-developed visualized ...

Analytical model for undrained residual shear strength of foam-conditioned coarse-grained soils in large deformation based on effective stress principle

Yantu gongcheng xuebao, 2023
Foam is usually used in soil conditioning of earth pressure balance shield tunnelling. The smooth muck discharge and chamber pressure transmission require foam-conditioned coarse-grained soils with suitable flowability to avoid face instability and ...

Defect‐Mediated Inelastic Light Scattering by Infrared Phonons in Hexagonal Boron Nitride

Advanced Functional Materials, EarlyView.
Optically active defects in hexagonal boron nitride enable inelastic stimulated light scattering mediated by infrared‐active phonons, relaxing conventional Raman selection rules. Defect engineering enhances the Stokes‐conversion process and activates both TO‐ and LO‐phonon scattering channels.

Shear Banding in Time-Dependent Flows of Complex Fluids [PDF]

, 2013
We explore theoretically the time-dependent rheological response of complex fluids to step stress, shear startup and strain ramp deformations. We study soft glassy materials and entangled polymeric materials above and below the glass transition using the

Experimental Study on the Shearing Behaviour on the Interface between Coarse Sand and Concrete under High Stress

Geofluids, 2021
The shear behaviour on the interface between soil and structure is a research hot point. Based on the RMT-150B rock mechanics test system, a series of high-stress direct tests were performed on the coarse sand under the condition of different moisture ...
