A discrete mechanical model of fractional hereditary materials [PDF]

open access: yes, 2013
Fractional hereditary materials are characterized for the presence, in the stress-strain relations, of fractional-order operators with order beta a[0,1]. In Di Paola and Zingales (J. Rheol.

On the generalized Laplace transform [PDF]

open access: yes, 2021
This article belongs to the Special Issue Discrete and Fractional Mathematics: Symmetry and Applications.In this paper we introduce a generalized Laplace transform in order to work with a very general fractional derivative, and we obtain the properties ...

An efficient method for the analytical study of linear and nonlinear time-fractional partial differential equations with variable coefficients [PDF]

open access: yes, 2023
The residual power series method is effective for obtaining approximate analytical solutions to fractional-order differential equations. This method, however, requires the derivative to compute the coefficients of terms in a series solution.

A Modified Fractional Derivative and its Application to Fractional Vibration Equation [PDF]

open access: yes, 2016
In this paper, a new modified definition of the fractional derivative is presented. The Laplace transform of the modified fractional derivative involves the initial values of the integer-order derivatives, but does not involve the initial values of the ...

Mathematical Models of Oscillators with Memory [PDF]

open access: yes, 2018
The chapter proposes a mathematical model for a wide class of hereditary oscillators, which is a Cauchy problem in the local formulation. As an initial model equation, an integrodifferential equation of Voltaire type was introduced, which was reduced by ...

Fractional calculus modelling for unsteady unidirectional flow of incompressible fluids with time-dependent viscosity

open access: yes, 2012
In this note we analyze a model for a unidirectional unsteady flow of a viscous incompressible fluid with time dependent viscosity. A possible way to take into account such behaviour is to introduce a memory formalism, including thus the time dependent ...
