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, ...
Determination of friction coefficient in unconfined compression of brain tissue
(Elsevier, 2012-10)
Unconfined compression tests are more convenient to perform on cylindrical
samples of brain tissue than tensile tests in order to estimate mechanical
properties of the brain tissue because they allow for homogeneous ...
Temperature effects on brain tissue in compression
(2012)
Extensive research has been carried out for at least 50 years to
understand the mechanical properties of brain tissue in order to understand the
mechanisms of traumatic brain injury (TBI). The observed large variability ...
Inhomogeneous deformation of brain tissue during tension tests
(Elsevier, 2012)
Mechanical characterization of brain tissue has been investigated
extensively by various research groups over the past 50 years. These properties
are particularly important for modeling Traumatic Brain Injury (TBI). ...
On the third- and fourth-order constants of incompressible isotropic elasticity.
(Acoustical Society of America, 2010-04-25)
Consider the constitutive law for an isotropic elastic solid with the strain-energy function expanded up to the fourth order in the strain and the stress up to the third order in the strain. The stress-strain relation can ...
Compression instabilities of tissues with localized strain softening.
(World Scientific Publishing Company, 2010-09-27)
The stress-strain relationship of biological soft tissues affected by Marfan's syndrome is believed to be nonconvex. More specifically, Haughton and Merodio recently proposed a strain energy density leading to localized ...
