Paper Highlight

Frequency domain identification of the fractional Kelvin-Voigt’s parameters for viscoelastic materials

M Shabani, K Jahani, M Di Paola, MH Sadeghi

Publication information: Mechanics of Materials Volume 137, October 2019, 103099

https://www.sciencedirect.com/science/article/pii/S0167663618308111

　

Abstract

In this work, a new innovative method is used to identify the parameters of fractional Kelvin-Voigt constitutive equation. These parameters are: the order of fractional derivation operator, 0 ≤ α ≤ 1, the coefficient of fractional derivation operator, CV, and the stiffness of the model, KV. A particular dynamic test setup is developed to capture the experimental data. Its outputs are time histories of the excitation and excited accelerations. The investigated specimen is a polymeric cubic silicone gel material known as α-gel. Two kinds of experimental excitations are used as random frequencies and constant frequency harmonic excitations. In this study, experimental frequency response functions confirm that increasing the static preload changes the behavior of the investigated viscoelastic material and the fractional Kelvin-Voigt model loses its validity by increasing the precompression. It is shown that, for a random frequencies excitation, by transforming from the time domain to the frequency domain the mentioned parameters can be identified. Using the identified parameters, analytical frequency response functions are so close to their experimental counterparts. Also, analytically produced time histories of the test setup’s output for steady-state experimental tests are so close to the captured time histories. The mentioned results validate the procedure of identification.

A non-local structural derivative model for memristor

Lin Qiu, Wen Chen, Fajie Wang, Ji Lin

Publication information: Chaos, Solitons & Fractals, Volume 126, September 2019, Pages 169-177
https://www.sciencedirect.com/science/article/pii/S096007791930205X

Abstract

The memristor is of great application and significance in the integrated circuit design, the realization of large-capacity non-volatile memories and the neuromorphic systems. This paper firstly proposes the non-local structural derivative memristor model with two-degree-of-freedom increased to portray the memory effect of memristor. Actually, the developed is a more generalized model that will be reduced to the classical one when the fractal characteristic index α = 1. The proposed model is more flexible than the classical ideal memory model and Riemann Liouville memristor model under the same conditions. In addition, the memory effect described by the present scheme could be adjusted by the position parameter δ. This work provides a new methodology not only to describe the memory effect of the memristor, but also to easily portray the memristor with ultra-weak memory.
