Investigation of strain rate sensitivity of polymer matrix composites [PDF]

open access: yes, 2004
Includes bibliographical references (leaves 210-219)An investigation into high strain rate behaviour of polymer composites was performed by developing a finite element model for a fibre reinforced polymer (FRP) plates impacted at varying strain rates ...

Application of optical measurement techniques to high strain rate deformations in composite materials [PDF]

open access: yes, 2010
Traditionally high strain rate material characterisations have been conducted using strain gauges and/or cross head displacements in servo-hydraulic test machines, and force transducers in split Hopkinson bar experiments.

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.
