Resumen
Este artículo presenta una metodología h-adaptativa jerárquica para el análisis de elementos finitos basado en las relaciones jerárquicas entre los elementos padre e hijo que aparecen si estos elementos son geométricamente similares. Bajo esta condición de similitud, los términos implicados en la evaluación de las matrices de rigidez de elementos de los elementos padre e hijo están relacionados por una constante que es una función de la relación de tamaños de elemento (factor de escala). Estas relaciones han sido la base para el desarrollo de una metodología h-adaptativa jerárquica basada en la subdivisión de elementos y el uso de restricciones multipunto para asegurar la continuidad C0. El uso de una estructura jerárquica de datos reduce significativamente la cantidad de cálculos requeridos para el refinamiento de la malla, la evaluación de la matriz de rigidez global, las tensiones de los elementos y la estimación del error del elemento. La estructura de datos también produce un reordenamiento natural de la matriz de rigidez global que mejora el comportamiento de la factorización de Cholesky.
