Incompressibility and Large Deformations
2017We present a new point of view on the motion of an incompressible solid with large deformations. The description of the shape changes of the solid involves the stretch matrix \(\mathbf {W}\) of the classical polar decomposition. The incompressibility condition is \(\det \mathbf {W}\,\ge \,1\), accounting for possible cavitation or phase change.

Leukocyte deformability: Finite element modeling of large viscoelastic deformation
Journal of Theoretical Biology, 1992An axisymmetric deformation of a viscoelastic sphere bounded by a prestressed elastic thin shell in response to external pressure is studied by a finite element method. The research is motivated by the need for understanding the passive behavior of human leukocytes (white blood cells) and interpreting extensive experimental data in terms of the ...

Stable deformations in large metallic clusters
Physical Review Letters, 1993Only a relatively small number of metallic clusters exhibit a stable spherical shape. We show that the majority of such clusters tend to acquire a deformed shape, in order to minimise the fluctuating part of the total energy, due to the bunching of the single particle electronic levels in a confined geometry.

Reconstructive elasticity imaging for large deformations
IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 1999A method is presented to reconstruct the elastic modulus of soft tissue based on ultrasonic displacement and strain images for comparatively large deformations. If the average deformation is too large to be described with a linear elastic model, nonlinear displacement-strain relations must be used and the mechanical equilibrium equations must include ...

Large Deformations of Polymers
2014The stress-strain behavior of polymers is described. The rheological equations of state for isotropic elastic materials are discussed as well as the equation of state for the ideal rubber. The theory of rubber elasticity is shortly presented.

Foundations of Large Deformations
1984In these lecture notes we will recapitulate some basic facts from the mechanics of a continuous medium at finite deformations, which are needed for the development of thermomechanical constitutive theory, presented in separate articles of this course on thermoplasticity.
