The tensile ductility of cellular solids: the role of imperfections
(Elsevier, 2016-10-11)
Metallic and polymeric foams typically possess a low tensile failure strain of a few percent despite the fact that the parent solid can have high ductility (10% or more). This is remarkable as foams are bending-dominated ...
Computational investigation of in situ chondrocyte deformation and actin cytoskeleton remodelling under physiological loading
(Elsevier, 2012-12-24)
Previous experimental studies have determined local strain fields for both healthy and degenerate cartilage tissue during mechanical loading. However, the biomechanical response of chondrocytes in situ, in particular the ...
The effect of remodelling and contractility of the actin cytoskeleton on the shear resistance of single cells: a computational and experimental investigation
(The Royal Society Publishing, 2012-07-18)
The biomechanisms that govern the response of chondrocytes to mechanical stimuli are poorly understood. In this study, a series of in vitro tests are performed, in which single chondrocytes are subjected to shear deformation ...
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, ...
