High strain rate response of UHP(FR)C in compression

open access: yesEPJ Web of Conferences, 2015
The objective of this study was to investigate the compression behaviour of the UHPFRC and its matrix (UHPC) under high strain rate. Two experimental set-ups were used for compression testing: a traditional Split Hopkinson Pressure Bars and a compression

Study on the Influence of Sample Size on the Mechanical and Integrity Characteristics of Coal Measure Sandstone under High Strain Rate

open access: yesFractal and Fractional, 2023
In order to explore the size effect of the mechanical and damage characteristics of coal measure sand stones under dynamic load, uniaxial impact compression tests were carried out on coal-bearing sand stones with a diameter of 50 mm and a length–diameter

Development of a D-xylose fermenting and inhibitor tolerant industrial Saccharomyces cerevisiae strain with high performance in lignocellulose hydrolysates using metabolic and evolutionary engineering [PDF]

open access: yes, 2013
Background: The production of bioethanol from lignocellulose hydrolysates requires a robust, D-xylose-fermenting and inhibitor-tolerant microorganism as catalyst.

Specimen Inertia in high strain rate tensile testing

open access: yesEPJ Web of Conferences, 2015
It is well established that measurements of the dynamic mechanical response of materials are susceptible to errors due to the inertia of the specimen, which causes stresses in addition to the intrinsic material strength.

In-Situ Nuclear Magnetic Resonance Investigation of Strain, Temperature, and Strain-Rate Variations of Deformation-Induced Vacancy Concentration in Aluminum [PDF]

open access: yes, 1998
Critical strain to serrated flow in solid solution alloys exhibiting dynamic strain aging (DSA) or Portevin–LeChatelier effect is due to the strain-induced vacancy production. Nuclear magnetic resonance (NMR) techniques can be used to monitor in situ the

Mechanical behavior of sand under high pressure and high strain rate

open access: yesEPJ Web of Conferences, 2012
Characterizing of the mechanical behavior of sand under impact loading is necessary to estimate the power of explosive mines. Using Hopkinson pressure bars for its characterization only low and limited pressures can be applied.
