基于多尺度晶体塑性有限元的GCr15轴承钢拉-压不对称性研究

open access: yesJixie qiangdu, 2021
In this paper,stress triaxiality is added to the classical crystal plasticity constitutive model to investigate the experimental phenomenon of tension-compression asymmetry for the GCr15 bearing steel.Firstly, the crystal plasticity constitutive model is

Statistical approach to dislocation dynamics: From dislocation correlations to a multiple-slip continuum plasticity theory [PDF]

open access: yes, 2007
Due to recent successes of a statistical-based nonlocal continuum crystal plasticity theory for single-glide in explaining various aspects such as dislocation patterning and size-dependent plasticity, several attempts have been made to extend the theory ...

Anomalous Plasticity of Body-Centered-Cubic Crystals with Non-Schmid Effect [PDF]

open access: yes, 2017
Plastic deformations in body-centered-cubic (BCC) crystals have been of critical importance in diverse engineering and manufacturing contexts across length scales. Numerous experiments and atomistic simulations on BCC crystals reveal that classical crystal plasticity models with the Schmid law are not adequate to account for abnormal plastic ...

Shock compression and spallation of single crystal tantalum [PDF]

open access: yes, 2012
We present molecular dynamics simulations of shock-induced plasticity and spall damage in single crystal Ta described by a recently developed embedded-atom-method (EAM) potential and a volumedependent qEAM potential.

Plastic-embedded protein crystals [PDF]

open access: yesJournal of Synchrotron Radiation, 2006
Rapid vitrification followed by the replacement of the vitrified water by a solvent (freeze substitution) and then resin is a widely used procedure for preparing biological samples for electron microscopy. The resulting plastic-embedded samples permit convenient room-temperature sectioning (microtomy) and can yield well preserved cellular structures ...

Phase diagram of colloidal hard superballs: from cubes via spheres to octahedra [PDF]

open access: yesSoft Matter, 2012, 8, 8826, 2011
The phase diagram of colloidal hard superballs, of which the shape interpolates between cubes and octahedra via spheres, is determined by free-energy calculations in Monte Carlo simulations. We discover not only a stable face-centered cubic (fcc) plastic crystal phase for near-spherical particles, but also a stable body-centered cubic (bcc) plastic ...

The atypical KRASQ22K mutation directs TGF‐β response towards partial epithelial‐to‐mesenchymal transition in patient‐derived colorectal cancer tumoroids

open access: yesMolecular Oncology, EarlyView.
TGF‐β has a complex role in cancer, exhibiting both tumor‐suppressive and tumor‐promoting properties. Using a series of differentiated tumoroids, derived from different stages and mutational background of colorectal cancer patients, we replicate this duality of TGF‐β in vitro. Notably, the atypical but highly aggressive KRASQ22K mutation rendered early‐

Microstructure-based crystal plasticity modeling of AA2024-T3 aluminum alloy defined as the α-Al, θ-Al2Cu, and S-Al2CuMg phases based on real metallographic image

open access: yesMaterials Research Express, 2021
The increase in the strength of the Al–Cu–Mg alloys is to a large extent due to the formation and distribution of submicroscopic θ -Al _2 Cu and S-Al _2 CuMg phases in the aluminum ( α -Al) matrix, which causes these alloys to have unique properties such
