On the strain-rate sensitivity of columnar ice [PDF]
Journal of Glaciology, 1997 AbstractA power law relation between stress and strain rate of the form was used to describe the response to strain rate of S1 ice loaded across the columns at –10° C. The rate exponent, n, decreased with increasing strain from about 4.6 at an observed peak on the load displacement curve to approximately 2.6 at a shortening of 2%.

Effect of oxygen contents on strain rate sensitivity of commercially pure titanium [PDF]
MATEC Web of Conferences, 2020 In this study, we have investigated the effect of oxygen contents on strain rate senstivitiy (SRS) within Gr. 1 and 4 commercially pure titanium (CP-Ti). The SRS was evaluated in multi-scales using macro-scopic tensile test with constant strain rate (CSR)

Investigation on the Strain Rate Sensitivity of Polytetrafluoroethylene
DEStech Transactions on Engineering and Technology Research, 2018 Strain rate sensitivity of polytetrafluoroethylene(PTFE) across strain rate range from 10-3 to 106 s-1 was investigated. For quasi-static state of strain rates from10-3 to 10-1 s-1, the samples were tested using universal material testing machine. The values of compression strength and Young’s Modulus were calculated from the experimental results.

Physical nature of strain rate sensitivity of metals and alloys at high strain rates [PDF]
Journal of Physics: Conference Series, 2018 The role of instabilities of plastic flow at plastic deformation of various materials is one of the important cross-disciplinary problems which is equally important in physics, mechanics and material science. The strain rate sensitivities under slow and high strain rate conditions of loading have different physical nature.

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.
