Strain-Rate-Dependent Phase Transition Mechanism in Polybutene1 during Uniaxial Stretching: From Quasi-Static to Dynamic Loading Conditions

open access: yes, 2022
With the assistance of an ultrafast time-resolved synchrotron radiation wide-angle X-ray diffraction technique and a homemade hyphenated high-speed tensile apparatus, structural evolutions in the crystalline domain of polybutene-1 (PB-1) are elucidated ...

Timing and rate of global contraction on Mercury

open access: yesGeophysical Research Letters, 2017
Impact bombardment and global contraction due to planetary cooling have both shaped the surface of Mercury over very long time scales. Landforms associated with these processes, i.e., impact craters and thrust fault‐related escarpments, and their mutual ...

Effect of strain rate on consolidation behavior of Ariake clay and selection of the suitable strain rate

open access: yesYantu gongcheng xuebao, 2017
The effect of strain rate on the consolidation behavior of Ariake clay is investigated by the constant rate of strain (CRS) consolidation tests under different strain rates, and the suitable stain rate in CRS consolidation tests is discussed based on the

Experimental study on effect of graded loading rate on creep characteristics of anthracite

open access: yesMeikuang Anquan, 2022
In order to study the effect of graded loading rate on creep characteristics of anthracite, the effects of graded loading rate and stress level on instantaneous strain, creep strain and creep rate of coal samples were analyzed by triaxial creep tests of

A Novel Electromechanical Apparatus for Intermediate Strain-Rate Testing and Validation on Polycarbonate

open access: yesApplied Sciences
The characterization of material behavior under intermediate deformation rates remains a major challenge, since conventional testing devices are mainly developed for either quasi-static or high strain-rate conditions.
