Continuum Modeling of Stress-Driven Surface Diffusion in Strained Elastic Materials
MRS Proceedings, 1993ABSTRACTThe free energy of a deformable crystal is assumed to consist of elastic strain energy and surface energy, and the chemical potential for surface diffusion at constant temperature is obtained under this assumption. The result is applied in considering the phenomena of instability of a flat surface in a stressed material under fluctuations in ...

A Model for Stress-Driven Diffusion in Polymers
1988Penetration of solvents into polymers is sometimes characterized by steep concentration gradients that move into the polymer and last for long times. The behavior of these fronts cannot be explained by standard diffusion equations, even with concentration dependent diffusion coefficients.

Journal of Volcanology and Geothermal Research, 2009
Abstract The occurrence of micron to millimeter size globular heterogeneities in igneous rocks is frequently explained by processes of liquid immiscibility. However, such textures have also been documented in miscible magmatic pairs. In this study, the ability of miscible magmas to develop transient surface tensions and mimic the behavior of ...

Dynamic nonlinear model with eddy current effect for stress-driven Galfenol energy
2015 IEEE Magnetics Conference (INTERMAG), 2015The energy harvester using magnetostrictive materials (e.g., Metglas, Terfenol-D and Galfenol) is receiving increased attention [1]-[5]. However, prediction of performance for the magnetostrictive harvester is complicated because the device exhibits nonlinear magnetomechanical coupling characteristics and the stress-induced eddy current loss, which is ...

Vibration analysis of stress-driven nonlocal integral model of viscoelastic axially FG nanobeams
The European Physical Journal Plus, 2020Finite element method (FEM) and generalized differential quadrature method (GDQM) are developed for damping vibration analysis of viscoelastic axially functionally graded (VAFG) nanobeams within the framework of stress-driven nonlocal integral model (SDM). The equivalent differential law of SDM and two constitutive non-classic boundary conditions (CBCs)

The stress driven instability in elastic crystals: Mathematical models and physical manifestations
Journal of Nonlinear Science, 1993Equilibrium equations and stability conditions for the simple deformable elastic body are derived by means of considering a minimum of the static energy principle. Considering the case of negligible magnitude of the surface tension, we establish that an equilibrium state of a nonhydrostatically stressed simple elastic body (of any physically reasonable

Leaf-Level Models of Constitutive and Stress-Driven Volatile Organic Compound Emissions
2013This chapter provides a review of past and contemporary leaf-level emission algorithms that have been and currently are in use for modelling the emissions of biogenic volatile organic compounds (BVOCs) from plants. The chapter starts with a brief overview about historical efforts and elaborates on processes that describe the direct emission responses ...

A stress-driven model for bone density evolution in rats during orthodontic tooth movement
Journal of the Mechanical Behavior of Biomedical MaterialsOrthodontic bone remodeling simulations offer a scientific foundation for optimizing treatment plans and predicting outcomes in orthodontics. Since alveolar bone exhibits unique regional responses and high sensitivity to tensile and compressive stresses, traditional models often fail to account for these characteristics, limiting their accuracy in ...

Coronary artery plaque growth: A two‐way coupled shear stress–driven model
International Journal for Numerical Methods in Biomedical Engineering, 2019AbstractAtherosclerosis in coronary arteries can lead to plaque growth, stenosis formation, and blockage of the blood flow supplying the heart tissue. Several studies have shown that hemodynamics play an important role in the growth of coronary artery plaques.
