A Hybrid Microstructural-Continuum Multiscale Approach for Modeling Hyperelastic Fibrous Soft Tissue [0.03%]
用于建模高弹性纤维软组织的混合细观-连续多尺度方法

The heterogeneous, nonlinear, anisotropic material behavior of biological tissues makes precise definition of an accurate constitutive model difficult. One possible solution to this issue would be to define microstructural elements and perf...

We present a study on planar equilibria of a terminally loaded elastic rod wrapped around a rigid circular capstan. Both frictionless and frictional contact between the rod and the capstan are considered. We identify three cases of friction...

Morphogenesis is regulated by genetic, biochemical, and biomechanical factors, but the feedback controlling the interactions between these factors remains poorly understood. A previous study has found that compressing the brain tube of the ...

The mechanics of most soft tissues in the human body are determined by the organization of their collagen fibers. Predicting how mechanics will change during growth and remodeling of those tissues requires constitutive laws that account for...
Mathematical Modelling of Residual-Stress Based Volumetric Growth in Soft Matter [0.03%]
软物质中基于残余应力的体积增长的数学模型

Growth in nature is associated with the development of residual stresses and is in general heterogeneous and anisotropic at all scales. Residual stress in an unloaded configuration of a growing material provides direct evidence of the mecha...
On an Implicit Model Linear in Both Stress and Strain to Describe the Response of Porous Solids [0.03%]
一种既与应力又与应变呈线性的隐式模型来描述多孔固体的响应特性分析

We study some mathematical properties of a novel implicit constitutive relation wherein the stress and the linearized strain appear linearly that has been recently put into place to describe elastic response of porous metals as well as mate...
Constrained Mixture Models of Soft Tissue Growth and Remodeling - Twenty Years After [0.03%]
软组织生长和重塑的约束混合模型——二十年后的回顾

Soft biological tissues compromise diverse cell types and extracellular matrix constituents, each of which can possess individual natural configurations, material properties, and rates of turnover. For this reason, mixture-based models of g...
Utilization of the Theory of Small on Large Deformation for Studying Mechanosensitive Cellular Behaviors [0.03%]
基于大变形小理论的力学敏感行为研究
Seungik Baek,Chun Liu,Kun Gou et al.
Seungik Baek et al.
Recent studies suggest that cells routinely probe their mechanical environments and that this mechanosensitive behavior regulates some of their cellular activities. The finite elasticity theory of small-on-large deformation (SoL) has been s...

The heart grows in response to changes in hemodynamic loading during normal development and in response to valve disease, hypertension, and other pathologies. In general, a left ventricle subjected to increased afterload (pressure overloadi...

Brain swelling is a serious condition associated with an accumulation of fluid inside the brain that can be caused by trauma, stroke, infection, or tumors. It increases the pressure inside the skull and reduces blood and oxygen supply. To r...
