Error Estimates and Analysis Results for Signorini’s Problem in Thermo-Electro-Viscoelasticity

EL-H. Essoufi , M. Alaoui , M. Bouallala

We consider a mathematical model describing the quasi-static process of contact between a thermo-electroviscoelastic body and a rigid foundation. The contact is described by Signorini’s conditions. The variational formulation leads to a coupled system for the displacement filed, the electric potential ...

Source to Coast Pollutants Distribution in Tangier Area: Arc GIS Interpolation and Finite Element Methods

Saiida Lazaar , Siham Abourida

This work attempts a contribution for studying marine pollution from a numerical point of view and aims to offer some solutions for the preservation of marine environment. For more reliability, Tangier bay (North of Morocco) was chosen as a study area. We underline that the main topic of this paper deals ...

Multiscale Fractal-Crack Interaction in Orthotropic Plates on Fractional Foundations Using Extended Finite Element Method and Fox H-Functions

Sule Adekunle JIMOH , Olorunsola Oriola Niyi , Adebola Samuel ADEOYE , E. C. Ajila

Cracked orthotropic plates resting on viscoelastic foundations exhibit complex dynamic responses due to the simultaneous influence of nonlocal elasticity, memory-dependent damping, and displacement discontinuities. Conventional models often fail to capture these effects in a unified manner, particularly ...
