Surface Reordering During Layer‐by‐Layer Growth on SrTiO3

Advanced Materials, EarlyView.
Surface structures (left) derived from DFT‐constrained fitting to crystal truncation rods measured by synchrotron X‐ray scattering (right) after each monolayer of deposition during the MBE growth of SrTiO3${\rm SrTiO}_{3}$ (001). The bottom panel shows the bare substrate, the middle panel shows island formation upon deposition of a single layer of SrO,

Application of an elastoplastic model to predict behaviors of Concrete-Faced Rock-fill Dam under complex loading conditions

Journal of Civil Engineering and Management, 2015
In this research, a simplified rotational kinematic hardening model with the concept of sub-loading was used to predict behaviors of Concrete-Faced Rock-fill Dam under complex loading conditions.

Models of nonlinear kinematic hardening based on different versions of rate-independent maxwell fluid [PDF]

, 2017
Different models of finite strain plasticity with a nonlinear kinematic hardening are analyzed in a systematic way. All the models are based on a certain formulation of a rate-independent Maxwell fluid, which is used to render the evolution of backstresses.

Finite strain viscoplasticity with nonlinear kinematic hardening: phenomenological modeling and time integration

, 2007
This article deals with a viscoplastic material model of overstress type. The model is based on a multiplicative decomposition of the deformation gradient into elastic and inelastic part.

Humid‐Air Condensation Heat Transfer on Hierarchical Structured Superhydrophobic Graphite Composites

Advanced Materials Interfaces, EarlyView.
Humid‐air condensation on graphite composites shows that making a surface superhydrophobic is not sufficient to enhance heat transfer. A hierarchical CuO/lauric‐acid coating yields spherical droplets but promotes Wenzel‐type pinning and adds effective thermal resistance under operation.

Anti‐Slip Material‐Based Strategies and Approaches

Advanced Materials Technologies, EarlyView.
This review highlights the principle mechanisms of slipping at the microscale, linking contact mechanics with a friction behavior model for surface interfaces. Main strategies to develop anti‐slip properties to the surfaces are discussed alongside standardized testing approaches.
