Behaviour of steel straps confined concrete column with lateral pre-tensioning stresses under uniaxial cyclic compression [PDF]

open access: yes, 2015
The behaviour of high strength concrete (HSC) under uniaxial cyclic compression load is extremely important to simulate the seismic effect. It is very helpful to the development of high rise building and future demand of HSC. The main problems of HSC are

Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

open access: yesAdvanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

LFA: A Lattice Fourier Analyzer for Quantitative In Situ EC‐STM of Adsorbate–Substrate Superstructures

open access: yesAdvanced Materials Interfaces, EarlyView.
Although electrochemical scanning tunneling microscopy provides atomic‐scale access to electrified interfaces, quantitative in situ and operando investigations suffer from drift‐induced distortions. This work introduces the Lattice Fourier Analyzer (LFA), which employs substrate‐anchored affine drift correction in reciprocal space to recover precise ...

A damage-plasticity model for the dynamic failure of concrete

open access: yes, 2011
A constitutive model based on the combination of damage mechanics and plasticity is developed to analyse concrete structures subjected to dynamic loading. The aim is to obtain a model, which requires input parameters with clear physical meanings.

A flat-joint contact model and meso analysis on mechanical characteristics of brittle rock

open access: yesKuwait Journal of Science, 2019
: At present, the traditional particle model is difficult to simulate the mechanical characteristics of brittle rock such as particle structure and the ratio of uniaxial tensile to uniaxial compressive strength (σt/σucs).

A Nonvolume Preserving Plasticity Theory with Applications to Powder Metallurgy [PDF]

open access: yes, 1983
A plasticity theory has been developed to predict the mechanical response of powder metals during hot isostatic pressing. The theory parameters were obtained through an experimental program consisting of hydrostatic pressure tests, uniaxial compression ...
