A Review on Capturing Twin Nucleation in Crystal Plasticity for Hexagonal Metals
Metals, 2021 Owing to its ability to incorporate Schmid’s law at each integration point, crystal plasticity has proven a powerful tool to simulate and predict the slip behavior at the grain level and the ensuing heterogeneous stress/strain localization and texture ...

DDX3X induces mesenchymal transition of endothelial cells by disrupting BMPR2 signaling
FEBS Open Bio, EarlyView.Elevated DDX3X expression led to downregulation of BMPR2, a key regulator of endothelial homeostasis and function. Our co‐immunoprecipitation assays further demonstrated a molecular interaction between DDX3X and BMPR2. Notably, DDX3X promoted lysosomal degradation of BMPR2, thereby impairing its downstream signaling and facilitating endothelial‐to ...

Journal of the Mechanical Behavior of Materials, 2012 Up to now, models for single crystal plasticity predict unbounded lattice rotations under simple shear. Asaro et al. proposed a model that predicts bounded rotations as long as the viscosity parameters are appropriately chosen.

A crystal plasticity FEM investigation of a Cu single crystal processed by accumulative roll-bonding
Journal of Materials Research and Technology, 2019 In this study, texture modelling of a copper single crystal processed by accumulative roll-bonding (ARB) was conducted for the first time. A crystal plasticity finite element method (CPFEM) model was developed, and the predicated textures were validated ...

FEBS Open Bio, EarlyView.KLK7, a tissue kallikrein‐related peptidase, is elevated in advanced colorectal cancer and associated with shorter survival. High KLK7 levels in ascites correlate with peritoneal metastasis. In mice, KLK7 overexpression increases metastasis. In vitro, KLK7 enhances cancer cell proliferation, migration, adhesion, and spheroid formation, driving ...

A three-dimensional multiscale model of intergranular hydrogen-assisted cracking [PDF]
, 2010 We present a three-dimensional model of intergranular hydrogen-embrittlement (HE) that accounts for: (i) the degradation of grain-boundary strength that arises from hydrogen coverage; (ii) grain-boundary diffusion of hydrogen; and (iii) a continuum model

Materials 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

Avalanches and plastic flow in crystal plasticity: an overview [PDF]
Modelling and Simulation in Materials Science and Engineering, 2017 Crystal plasticity is mediated through dislocations, which form knotted configurations in a complex energy landscape. Once they disentangle and move, they may also be impeded by permanent obstacles with finite energy barriers or frustrating long-range interactions.
