FORMABILITY OF AUSTENITIC STAINLESS STEEL 316 SHEET IN DYNAMIC STRAIN AGING REGIME

open access: yesActa Metallurgica Slovaca, 2014
Dynamic strain aging region for austenitic stainless steel 316 was investigated from room temperature to 650°C at constant strain rates of 1x10-2, 1x10-3 and 1x10-4 sec-1.

Effects of a strain rate sensitive material on the optimization of an hydroforming process

open access: yes, 2008
International audienceThe hydroforming process of a T-tube is simulated with the finite element code ABAQUS. The influence of the internal pressure and the axial displacement levels on the final tube quality is evaluated through a "process diagram".

A Micromechanical Model of Hardening, Rate Sensitivity and Thermal Softening in BCC Single Crystals [PDF]

open access: yes, 2001
The present paper is concerned with the development of a micromechanical model of the hardening, rate-sensitivity and thermal softening of bcc crystals. In formulating the model we specifically consider the following unit processes: double-kink formation

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

open access: yesFEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

The strain-rate effect of engineering materials and its unified model

open access: yesLatin American Journal of Solids and Structures
The test data of metals, brittle materials and polymers in high, medium and low strain-rate range were summarized. It was found that the dynamic strength or yield stress of these materials was not sensitive to strain-rate in the low and high strain-rate ...

Unraveling the temperature dependence of the yield strength in single-crystal tungsten using atomistically-informed crystal plasticity calculations

open access: yes, 2015
We use a physically-based crystal plasticity model to predict the yield strength of body-centered cubic (bcc) tungsten single crystals subjected to uniaxial loading.

Anomalous Strain Rate Effect in Ultrafine Grained Titanium [PDF]

open access: yes, 1899
An anomalous effect was found in the strain rate dependence of severe plastic deformed commercially pure titanium with ultrafinegrained structure. A maximum tensile strength was obtained for ϵ˙=10−3s−1. This did not allow a single strain rate sensitivity

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

open access: yesFEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Large‐scale bidirectional arrayed genetic screens identify OXR1 and EMC4 as modifiers of αSynuclein aggregation

open access: yesFEBS Open Bio, EarlyView.
Activation of the mitochondrial protein OXR1 increases pSyn129 αSynuclein aggregation by lowering ATP levels and altering mitochondrial membrane potential, particularly in response to MSA‐derived fibrils. In contrast, ablation of the ER protein EMC4 enhances autophagic flux and lysosomal clearance, broadly reducing α‐synuclein aggregates.

Strain rate sensitivity metrics of PSU and PPSU high-performance polymers in extrusion-based additive manufacturing

open access: yesResults in Engineering
High-performance polymers (HPPs), combined with material extrusion (MEX) additive manufacturing (AM), compile a powerful manufacturing system, suitable to meet the challenges of demanding industries. Their ability to undergo high strain rates is not well
