Plasticity without phenomenology: a first step
A novel, concurrent multiscale approach to meso/macroscale plasticity is demonstrated. It utilizes a carefully designed coupling of a partial differential equation (pde) based theory of dislocation mediated crystal plasticity with time-averaged inputs ...

Metal Crystal/Polycrystal Plasticity and Strengths
A brief historical sketch is given of Taylor’s dislocation density-based model description, leading to the prediction of a parabolic, tensile, stress–strain curve for the plastic deformation of aluminum.

Yielding and irreversible deformation below the microscale: Surface effects and non-mean-field plastic avalanches [PDF]
Nanoindentation techniques recently developed to measure the mechanical response of crystals under external loading conditions reveal new phenomena upon decreasing sample size below the microscale.

Cooperativity in plastic crystals
A statistical mechanical model previously adopted for the analysis of the α-relaxation in structural glass formers is rederived within a general theoretical framework originally developed for systems approaching the ideal glassy state. The interplay between nonexponentiality and cooperativity is reconsidered in the light of energy landscape concepts ...

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
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

Emerging role of ARHGAP29 in melanoma cell phenotype switching
This study gives first insights into the role of ARHGAP29 in malignant melanoma. ARHGAP29 was revealed to be connected to tumor cell plasticity, promoting a mesenchymal‐like, invasive phenotype and driving tumor progression. Further, it modulates cell spreading by influencing RhoA/ROCK signaling and affects SMAD2 activity. Rho GTPase‐activating protein
