Atherosclerotic Plaque Segmentation Based on Strain Gradients: A Theoretical Framework
Mathematics, 2022 Background: Atherosclerotic plaque detection is a clinical and technological problem that has been approached by different studies. Nowadays, intravascular ultrasound (IVUS) is the standard used to capture images of the coronary walls and to detect ...

Theory and computation of higher gradient elasticity theories based on action principles [PDF]
, 2017 In continuum mechanics, there exists a unique theory for elasticity, which includes the first gradient of displacement. The corresponding generalization of elasticity is referred to as strain gradient elasticity or higher gradient theories, where the ...

Extraordinary strain hardening by gradient structure [PDF]
Proceedings of the National Academy of Sciences, 2014 Significance Nature creates the gradient structure (GS) for a purpose: to make biological systems strong and tough to survive severe natural forces. For the grain-size GS, the deformation physics is still unclear. One wonders if the grain-size GS in the nanomicroscale would also benefit materials engineered by mankind.

Decay of solutions for strain gradient mixtures
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2022 AbstractWe study antiplane shear deformations for isotropic and homogeneous strain gradient mixtures of the Kelvin‐Voigt type in a cylinder. Our aim is to analyze the behaviour of the solutions with respect to the time variable when a dissipative structural mechanism is considered. We study three different cases, each at a time.

Possibilities of the practical use of a stationary strain gradient in the interelectrode volume of unpolarized ferroceramic plates [PDF]
Journal of Advanced Dielectrics, 2020 It has been established that in plates made of hot-pressed ferroelectric ceramics PZT-19 (Tc=300∘C), after metal electrodes from Ag are burned into opposite surfaces with different depths of mechanical damage, counter-directional stationary deformation ...

A theory of strain-gradient plasticity with effect of internal microforce [PDF]
Theoretical and Applied Mechanics, 2017 This paper develops a theory of strain gradient plasticity for isotropic bodies undergoing small deformation in the absence of plastic spin. The proposed theory is based on a system of microstresses which include a microstress vector consistent with ...
