A two-dimensional model for stress driven diffusion in bone tissue
Computer Methods in Biomechanics and Biomedical Engineering, 2013The growth and resorption of bone are governed by interaction between several cells such as bone-forming osteoblasts, osteocytes, lining cells and bone-resorbing osteoclasts. The cells considered in this study reside in the periosteum. Furthermore, they are believed to be activated by certain substances to initiate bone growth.

Finite Element Modeling of Avascular Tumor Growth Using a Stress-Driven Model
Journal of Biomechanical Engineering, 2017Tumor growth being a multistage process has been investigated from different aspects. In the present study, an attempt is made to represent a constitutive-structure-based model of avascular tumor growth in which the effects of tensile stresses caused by collagen fibers are considered. Collagen fibers as a source of anisotropy in the structure of tissue

Lattice modelling of gravity and stress-driven failures of rock tunnels
Computers and Geotechnics, 2019Abstract In this paper, an investigation is performed regarding the applicability of the Rigid Body Spring Network method (RBSN) to the analysis of hard rock tunnels in massive and fractured rock masses. For this objective, the method is enhanced with a new meshing scheme and a Cohesive Zone Model (CZM) formulation based on an exponential softening ...

Shocks in a Model for Stress-Driven Diffusion
SIAM Journal on Applied Mathematics, 1990Diffusion of a solvent into a polymer slab is sometimes characterized by a sharp front that moves into the medium and lasts for a long time. The behavior of such a front cannot be explained by a standard diffusion equation. Model equations are proposed that include solvent flux due to stress gradients in the polymer in addition to the Fickian flux. The

Constitutive modeling of stress-driven grain growth in nanocrystalline metals
Modelling and Simulation in Materials Science and Engineering, 2013In this work, we present a variational multiscale model for grain growth in face-centered cubic nanocrystalline (nc) metals. In particular, grain-growth-induced stress softening and the resulting relaxation phenomena are addressed. The behavior of the polycrystal is described by a conventional Taylor-type averaging scheme in which the grains are ...

A Nonlocal Finite Element Approach for Nanobeams Based on Stress-Driven Model [PDF]
Cureus Journal of EngineeringThe manuscript proposes a nonlocal finite element approach for the analysis of the bending behavior of Bernoulli-Euler nanobeams, based on well-posed Stress-Driven nonlocal continuum mechanics. The structural behavior of the nanobeams was investigated using COMSOL Multiphysics® 6.2.

Nitric Oxide, 2021
Major depression is accompanied by increased IgM-mediated autoimmune responses to oxidative specific epitopes (OSEs) and nitric oxide (NO)-adducts. These responses were not examined in bipolar disorder type 1 (BP1) and BP2. IgM responses to malondialdehyde (MDA), phosphatidinylinositol, oleic acid, azelaic acid, and NO-adducts were determined in 35 ...
