“…The second branch of error estimators, related with the concept of dual analysis, makes use of two solutions, one compatible and one equilibrated. Some of these error estimators solve two global problems in parallel [10] whereas other post-process the FE solution [11,12,13]. Under this group we can also include the error estimators based on the Constitutive Relation Error (CRE) introduced by Ladevèze and Leguillon [11] and followed by several contributions for many applications, see for example [14,15,16,17].…”

“…En segundo lugar, Kvamsdal y Okstad tan solo logran una aproximación de baja calidad de la satisfacción de las condiciones de equilibrio de Neumann en el contorno, ya que solamente consideran una minimización del residuo de la ecuación de equilibrio en el contorno. Pereira et al (1999) presentaron una técnica de evaluación de cotas superiores del error basada en el concepto del análisis dual para problemas elástico lineales. En general, para un espacio de aproximación dado, la soluciónóptima es tal que las tensiones son discontinuas y las deformaciones incompatibles.…”

“…La técnica de acotación del error propuesta por Pereira et al (1999) tiene el inconveniente del costo adicional asociado a la resolución de un segundo problema global. No obstante, ambos modelos se pueden resolver en paralelo.…”
