Exponential attractors for abstract equations with memory and applications to viscoelasticity [PDF]

open access: yes, 2014
We consider an abstract equation with memory of the form $$\partial_t \boldsymbol{x}(t)+\int_{0}^\infty k(s) \boldsymbol{A}\boldsymbol{x}(t-s){\rm d} s+\boldsymbol{B}\boldsymbol{x}(t)=0$$ where $\boldsymbol{A},\boldsymbol{B}$ are operators acting on some

Enhancing Fatigue Crack Growth Resistance in Heterostructured Aluminum Bimetals by Tailored Interface Design

open access: yesAdvanced Engineering Materials, EarlyView.
Different Al/Al bimetals with a single engineered interface reveal how mechanical mismatch governs fatigue crack growth under cyclic loading. Additionally, loading–unloading–reloading tests link the microyielding behavior to the fatigue crack growth resistance, while crack‐path analysis reveals toughening mechanisms at the interface, highlighting ...

Robust exponential attractors for Coleman-Gurtin equations with dynamic boundary conditions possessing memory

open access: yesElectronic Journal of Differential Equations, 2016
Well-posedness of generalized Coleman-Gurtin equations equipped with dynamic boundary conditions with memory was recently established by the author with C. G. Gal. In this article we report advances concerning the asymptotic behavior and stability of

The phase-space view of non-local gravity cosmology

open access: yesPhysics Letters B, 2022
We consider non-local Integral Kernel Theories of Gravity in a homogeneous and isotropic universe background as a possible scenario to drive the cosmic history.

A construction of a robust family of exponential attractors [PDF]

open access: yesProceedings of the American Mathematical Society, 2005
Given a dissipative strongly continuous semigroup depending on some parameters, we construct a family of exponential attractors which is robust, in the sense of the symmetric Hausdorff distance, with respect to (even singular) perturbations.

Existence and Continuity of Uniform Exponential Attractors of the Singularity Perturbed Hodgkin–Huxley System [PDF]

open access: yes, 1998
In order to show that the standard partially dissipative Hodgkin–Huxley system approximates the hyperbolic Hodgkin–Huxley system for large time, we are interested in establishing the existence of exponential attractors for the hyperbolic system with ...

Microstructure Modification of Additively Manufactured Mo–9Si–8B by Annealing and Its Effects on High‐Temperature Mechanical Properties

open access: yesAdvanced Engineering Materials, EarlyView.
Postbuild annealing systematically modifies the phase fractions and morphology of EB‐PBF processed Mo–9Si–8B. Quantitative microstructure–property correlations reveal how controlled phase evolution enhances high‐temperature compressive strength and creep resistance.

FIXED POINT OF CONTRACTION AND EXPONENTIAL ATTRACTORS

open access: yes, 2020
. The exponential attractor is known as one of useful notions of invariant attractors in the theory of infinite-dimensional dynamical systems. It is also known that, if the semigroup of a dynamical system satisfies a compact perturbation condition of ...

Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...
