The Role of Compressibility in Modified Quasi-Linear Viscoelasticity: A Comparison of Simple Shear and Torsion
Valentina Balbi, Griffen Small
We investigate the role of compressibility in the modified quasi-linear viscoelastic (MQLV) constitutive framework for soft solids at finite strain, where shear and bulk responses…
Programmable wrinkling for functionally-graded auxetic circular membranes
Sairam Pamulaparthi Venkata, Valentina Balbi, Michel Destradea +2
Materials with negative Poisson's ratio, also known as auxetic materials, display exotic properties such as expansion in all directions under uni-axial tension. For their unique pr…
Canceling the elastic Poynting effect with geometry
M. Destrade, Y. Du, J. Blackwell +2
The Poynting effect is a paragon of nonlinear soft matter mechanics. It is the tendency (found in all incompressible, isotropic, hyperelastic solids) exhibited by a soft block to e…
Modelling the non-linear viscoelastic behaviour of brain tissue in torsion
G. Small, F. Ballatore, C. Giverso +1
Brain tissue accommodates non-linear deformations and exhibits time-dependent mechanical behaviour. The latter is one of the most pronounced features of brain tissue, manifesting i…
Designing necks and wrinkles in inflated auxetic membranes
Sairam Pamulaparthi Venkata, Valentina Balbi, Michel Destrade +1
This article presents the potentiality of inflatable, functionally-graded auxetic membranes to produce wrinkles and necks. We obtain elastic instabilities at desired locations in a…
Foundations of viscoelasticity and application to soft tissues mechanics
Michele Righi, Valentina Balbi
Soft tissues are complex media, they display a wide range of mechanical properties such as anisotropy and non-linear stress-strain behaviour. They undergo large deformations and th…
