In this work, we study, from the numerical point of view, a type III thermoelastic model with double porosity. The thermomechanical problem is written as a linear system composed of hyperbolic partial differential equations for the displacements and

This paper addresses the numerical resolution of controllability problems for partial differential equations (PDEs) by using physics-informed neural networks. Error estimates for the generalization error for both state and control are derived from cl

In this paper, we study a quadratic nonlinear equation from the fractional point of view. An explicit solution is given in terms of the Lambert special function. A new phenomenon appears involving the collapsing of the solution and the blow-up of the

La teoría de la elasticidad impartida en grados de ingeniería se restringe a las hipótesis de linealidad (comportamiento elástico y pequeñas deformaciones). Esta hipótesis es perfectamente válida para el análisis de sistemas estructurales suj
