Evidence of new twinning modes in magnesium questioning the shear paradigm
, 2017 Twinning is an important deformation mode of hexagonal close-packed metals. The crystallographic theory is based on the 150-years old concept of simple shear. The habit plane of the twin is the shear plane, it is invariant.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

The Effects of Shear on Mode II Delamination: A Critical Review [PDF]
Fracture and Structural Integrity, 2018 The paper focuses on the effects of shear deformation and shear forces on the mode II contribution to the energy release rate in delaminated beams. A critical review of the relevant literature is presented, starting from the end-notched flexure test as ...

Pressure-dependent flow behavior of Zr_(41.2)Ti_(13.8)Cu_(12.5)Ni_(10)Be_(22.5) bulk metallic glass [PDF]
, 2003 An experimental study of the inelastic deformation of bulk metallic glass Zr_(41.2)Ti_(13.8)Cu_(12.5)Ni_(10)Be_(22.5) under multiaxial compression using a confining sleeve technique is presented. In contrast to the catastrophic shear failure (brittle) in

$1/f$ noise and avalanche scaling in plastic deformation [PDF]
, 2006 We study the intermittency and noise of dislocation systems undergoing shear deformation. Simulations of a simple two-dimensional discrete dislocation dynamics model indicate that the deformation rate exhibits a power spectrum scaling of the type $1/f ...

Near‐Field Electrospinning Micro‐Printhead Achieves Precise Control of Nanofiber Deposition
Advanced Engineering Materials, EarlyView.A micro‐printhead for near‐field electrospinning enables reproducible deposition of polymer nanofibers with diameters below 50 nm. Systematic parameter studies uncover the mechanisms linking operating conditions to fiber morphology, paving the way for precise and low‐cost nanoscale 3D manufacturing.As a high‐resolution, cost‐effective, and rapid ...

Effects of cyclic loading on lateral bearing capacity of single pile in silty seabed
Yantu gongcheng xuebaoUnder larger wave loading, the bearing capacity of marine single pile foundation will be reduced, even instability occurs. A series of undrained shear triaxial tests on the remolded marine silt in Hangzhou Bay are carried out by means of the GDS triaxial

Shear deformation laminate theory used for sandwiches [PDF]
Metalurgija, 2011 The shear deformation laminate theory is very useful for the calculation of the sandwich composites. Sandwich can be defined as a special laminate with three layers and therefore can be modeled using shear deformation laminate theory by neglecting of ...
