A thermodynamically motivated model for stress-fiber reorganization
(Springer Verlag, 2015-09-04)
We present a model for stress-fiber reorganization and the associated contractility that includes both the kinetics of stress-fiber formation and dissociation as well as the kinetics of stress-fiber remodeling. These ...
Cellular contractility and substrate elasticity: a numerical investigation of the actin cytoskeleton and cell adhesion
(Springer Verlag, 2013-06-18)
Numerous experimental studies have established that cells can sense the stiffness of underlying substrates and have quantified the effect of substrate stiffness on stress fibre formation, focal adhesion area, cell traction, ...
Evaluation of a multiscale modelling methodology to predict the mechanical properties of PCL/β-TCP sintered scaffold materials
(Springer Verlag, 2014-12-02)
A multiscale modelling methodology to predict the macroscale stiffness of selective laser sintered polycaprolactone (PCL)/β-tricalcium phosphate (β-TCP) materials is evaluated. The relationship between a micromechanics-evaluated ...
A unified viscoplastic model for high temperature low cycle fatigue of service-aged P91 steel
(American Society of Mechanical Engineers, 2014-01-07)
The finite element (FE) implementation of a hyperbolic sine unified cyclic viscoplasticity model is presented. The hyperbolic sine flow rule facilitates the identification of strain-rate independent material parameters for ...
Effects of material thickness and processing method on poly(lactic-co-glycolic acid) degradation and mechanical performance
(Springer Verlag, 2016-09-02)
In this study, the effects of material thickness and processing method on the degradation rate and the changes in the mechanical properties of poly(lactic-co-glycolic acid) material during simulated physiological degradation ...
Improving the finite element model accuracy of tissue engineered scaffolds produced by selective laser sintering
(Springer Verlag, 2015-01-13)
In bone tissue engineering, both geometrical and mechanical properties of a scaffold play a major part in the success of the treatment. The mechanical stresses and strains that act on cells on a scaffold in a physiological ...
