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 ...
Influence of initial residual stress on growth and pattern creation for a layered aorta
(Nature Research, 2019-06-03)
Residual stress is ubiquitous and indispensable in most biological and artificial materials, where it sustains and optimizes many biological and functional mechanisms. The theory of volume growth, starting from a stress-free ...
Electro-mechanical response of a 3D nerve bundle model to mechanical loads leading to axonal injury
(Wiley, 2017-11-21)
Traumatic brain injuries and damage are major causes of death and disability. We propose a 3D fully coupled electro-mechanical model of a nerve bundle to investigate the electrophysiological impairments due to trauma at ...
Wrinkles in soft dielectric plates
(Elsevier, 2018-07-04)
We show that a smooth giant voltage actuation of soft dielectric plates is not easily obtained in practice. In principle one can exploit, through pre-deformation, the snap-through behavior of their loading curve to deliver ...
Effects of nerve bundle geometry on neurotrauma evaluation
(Wiley, 2018-06-16)
ObjectiveWe confirm that alteration of a neuron structure can induce abnormalities in signal propagation for nervous systems, as observed in brain damage. Here, we investigate the effects of geometrical changes and damage ...
Pattern evolution in bending dielectric-elastomeric bilayers
(Elsevier, 2019-07-24)
We propose theoretical and numerical analyses of smart bending deformation of a dielectric-elastic bilayer in response to a voltage, based on the nonlinear theory of electro-elasticity and the associated linearized incremental ...
