Toward a predictive assessment of stab-penetration forces
(Lippincott, Williams & Wilkins, 2015-09)
Collaborative research between the disciplines of forensic pathology and biomechanics was undertaken to investigate the hyperelastic properties of human skin, to determine the force required for sharp instrument penetration ...
Introduction to the special issue on stability under finite deformation
(Oxford University Press, 2010)
In the botanical gardens of Grenoble, France, there is small bridge, just a few metres long, made of pre-stressed concrete. The bridge dates back to 1855 and is thought to be the oldest manufactured pre-stressed structure ...
Non-invasive evaluation of skin tension lines with elastic waves
(Wiley, 2017-11-20)
Background: Since their discovery by Karl Langer in the 19th Century, Skin Tension Lines (STLs) have been used by surgeons to decide the location and orientation of an incision. Although these lines are patient-specific, ...
Wrinkles in the opening angle method
(Elsevier, 2017-06-10)
We investigate the stability of the deformation modeled by the opening angle method, often used to give a measure of residual stresses in arteries and other biological soft tubular structures. Specifically, we study the ...
Oblique wrinkles
(The Royal Society Publishing, 2017-04-03)
We prove theoretically that when a soft solid is subjected to an extreme deformation, wrinkles can form on its surface at an angle that is oblique to a principal direction of stretch. These oblique wrinkles occur for a ...
Strain rate effects on the failure characteristics of excised human skin
(The 9th International Conference on the Mechanics of Time Dependent Materials, 2014)
Skin is a complex, multi-layered material which exhibits non-linear, anisotropic and viscoelastic
behaviour. Its structure is complex and can be broadly divided into three main layers: the
epidermis, the dermis and ...
Modified multiplicative decomposition model for tissue growth: Beyond the initial stress-free state
(Elsevier, 2018-05-19)
The multiplicative decomposition model is widely employed for predicting residual stresses and morphologies of biological tissues due to growth. However, it relies on the assumption that the tissue is initially in a ...
Torsion instability of soft solid cylinders
(Oxford Open Journals, 2013-12-10)
The application of pure torsion to a long and thin cylindrical rod is known to provoke a twisting instability, evolving from an initial kink to a knot. In the torsional parallel-plate rheometry of stubby cylinders, the ...
Mechanical characterization of brain tissue in tension at dynamic strain rates
(Elsevier, 2012-09-10)
Mechanical characterization of brain tissue at high loading velocities is crucial for modeling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences compression, tension and shear. Limited ...
Hyperelastic and viscoelastic properties of brain tissue in tension
(ASME, 2012)
Mechanical characterization of brain tissue at high loading velocities is particularly important for modelling Traumatic Brain Injury (TBI). During severe impact conditions, brain tissue experiences a mixture of compression, ...
