Coupling effect of deformation temperature and strain rate on mechanical properties in TWIP Ti-15Mo alloy

Cailiao gongcheng, 2022
Both deformation temperature and strain rate affect the mechanical properties of β titanium alloy, and are related to the change of deformation mode in the process of plastic deformation. The effects of deformation temperature and strain rate coupling on

New approach for determination of strain rate sensitivity of mild steel dc01 under stack compression and uniaxial tensile test [PDF]

, 2019
Deformation under uniaxial tensile loading with using Digital Image Correlations (DIC) is the easiest way to analyze the material behavior in sheet metal forming.

Effect of strain rate on the yielding mechanism of amorphous metal foam [PDF]

, 2010
Stochastic amorphous Pd_(43)Ni_(10)Cu_(27)P_(20) foams were tested in quasistatic and dynamic loading. The strength/porosity relations show distinct slopes for the two loading conditions, suggesting a strain-rate-induced change in the foam yielding ...

In vitro models of cancer‐associated fibroblast heterogeneity uncover subtype‐specific effects of CRISPR perturbations

Molecular Oncology, EarlyView.
Development of therapies targeting cancer‐associated fibroblasts (CAFs) necessitates preclinical model systems that faithfully represent CAF–tumor biology. We established an in vitro coculture system of patient‐derived pancreatic CAFs and tumor cell lines and demonstrated its recapitulation of primary CAF–tumor biology with single‐cell transcriptomics ...

Measurements of Strain-Rate Distributions on Material After Shpb Impact

Engineering Transactions, 2014
We have proposed a sophisticated novel method of the SHPB experiment to measure the local strain-rate distributions on a surface of the specimen by using mechanoluminescent materials combined with a high-speed camera and an image intensifier.

Strain-Rate Frequency Superposition in Large-Amplitude Oscillatory Shear

, 2010
In a recent work, Wyss, {\it et.al.} [Phys. Rev. Lett., {\bf 98}, 238303 (2007)] have noted a property of `soft solids' under oscillatory shear, the so-called strain-rate frequency superposition (SRFS).

Correlation of the differential expression of PIK3R1 and its spliced variant, p55α, in pan‐cancer

Molecular Oncology, EarlyView.
PIK3R1 undergoes alternative splicing to generate the isoforms, p85α and p55α. By combining large patient datasets with laboratory experiments, we show that PIK3R1 spliced variants shape cancer behavior. While tumors lose the protective p85α isoform, p55α is overexpressed, changes linked to poorer survival and more pronounced in African American ...

High strain rate behaviour of polypropylene microfoams

EPJ Web of Conferences, 2012
Microcellular materials such as polypropylene foams are often used in protective applications and passive safety for packaging (electronic components, aeronautical structures, food, etc.) or personal safety (helmets, knee-pads, etc.).

Relaxation oscillations and negative strain rate sensitivity in the Portevin - Le Chatelier effect

, 2000
A characteristic feature of the Portevin - Le Chatelier effect or the jerky flow is the stick-slip nature of stress-strain curves which is believed to result from the negative strain rate dependence of the flow stress.

X-ray microtomographic characterization and quantification of the strain rate dependent failure mechanism in cenosphere epoxy syntactic foams [PDF]

, 2016
This work investigates the failure mechanism in cenosphere epoxy syntactic foams at the quasi-static and dynamic strain rates. Split-Hopkinson pressure bar experiments are controlled to stop dynamic deformation of the foams at various strain stages.
