Análisis numérico de una formulacion para el problema de fluencia transiente

Abstract

En este trabajo analizamos el problema de fluencia transiente o de elasto-fluencia, para lo cual presentamos una nueva formulación mixta y demostramos el carácter asintótico de la solución. Para obtener la solución de este problema, utilizamos el método de elementos finitos en la aproximación espacial y el esquema de Euler implícito en la discretización temporal. Demostramos estabilidad y convergencia, y presentamos cotas de error para las soluciones de los problemas semi-discreto y totalmente discreto, mostrando que ellos conservan el carácter asintótico de la solución del problema continuo.
