Coupled reaction-diffusion waves in a chemical system via fractional derivatives in Liouville-Caputo sense

open access: yes
In this paper, we have generalized the fractional cubic isothermal auto-catalytic chemical system (FCIACS) with Liouville-Caputo, Caputo- Fabrizio-Caputo, and Atangana-Baleanu-Caputo fractional time derivatives, respectively.

Nonlinear heat-wave propagation in rigid thermal conductors via a distributed-order Caputo fractional model

open access: yesNonlinear Engineering
In this paper, a distributed–order Caputo fractional derivative is used to represent nonlinear heat wave propagation in rigid thermal conductors using a novel numerical approach. The suggested model takes into consideration memory effects that are a part

Petrov-Galerkin method for small deflections in fourth-order beam equations in civil engineering

open access: yesNonlinear Engineering
This study explores the Petrov–Galerkin method’s application in solving a linear fourth-order ordinary beam equation of the form u″″+qu=fu^{\prime\prime} ^{\prime\prime} +qu=f.

Penalty method for unilateral contact problem with Coulomb's friction in time-fractional derivatives

open access: yesDemonstratio Mathematica
The purpose of this work is to study a mathematical model that describes a contact between a deformable body and a rigid foundation. A linear viscoelastic Kelvin-Voigt constitutive law with time-fractional derivatives describes the material’s behavior ...
