Numerical modeling of strain rate hardening effects on viscoplastic behavior of metallic materials [PDF]
, 2017 The main goal of the present work is to provide a finite strain elasticviscoplastic framework to numerically account for strain, strain rate hardening, and viscous effects in cold deformation of metallic materials. The aim is to provide a simple and robust

Tau acetylation at K331 has limited impact on tau pathology in vivo
FEBS Letters, EarlyView.We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

Experimental study of the high strain rate shear behaviour of Ti6Al4V [PDF]
, 2011 Three different high strain rate shear test techniques are applied on the titanium alloy Ti6Al4V. Two techniques for testing of bulk materials and one technique for sheet materials are used: torsion of thin-walled tubes, compression of hat-shaped ...

Characterisation and modelling of structural bonding at high strain rate
EPJ Web of Conferences, 2012 These paper deals with the development of new bonded joint modelling for crash application. A new testing device has been set up on Split Hopkinson bars in order to identify adhesive’s properties in assemblies for high strain rate and for different ...

High strain-rate response of additively manufactured light metal alloys
Materials & Design, 2022 Understanding the high strain-rate response of materials is essential in applications including aerospace, automotive, and defence. Structures of these applications are often subjected to dynamic loadings of high strain rates and need to mitigate the ...

High strain-rate deformation analysis of open-cell aluminium foam
Journal of Materials Research and Technology, 2023 This study investigated the high-strain rate mechanical properties of open-cell aluminium foam M-pore®. While previous research has examined the response of this type of foam under quasi-static and transitional dynamic loading conditions, there is a lack

Realistic time-scale fully atomistic simulations of surface nucleation of dislocations in pristine nanopillars [PDF]
, 2012 We use our recently proposed accelerated dynamics algorithm (Tiwary and van de Walle, 2011) to calculate temperature and stress dependence of activation free energy for surface nucleation of dislocations in pristine Gold nanopillars under realistic loads.
