Optimización Topológica, MITC4, Estructuras de pared delgada, Campo no lineal geométricoResumo
El presente trabajo aborda la optimización topológica aplicada a estructuras de pared delgada, modeladas mediante elementos finitos de cáscara MITC4 en campo geométricamente no lineal. El problema se plantea como la minimización de la end compliance sujeta a una restricción de volumen, con el fin de obtener diseños aligerados sin comprometer la respuesta mecánica. La herramienta numérica desarrollada fue validada contra resultados disponibles en la literatura para respuestas tanto en el plano (in-plane) como fuera del plano (out-of-plane), demostrando la versatilidad y robustez de la formulación utilizada. Finalmente, se presenta una aplicación de interés industrial en un panel B de un chasis automotriz, donde se logró obtener piezas optimizadas de menor peso bajo diferentes fracciones de material sólido permitidas, manteniendo la satisfacción de las condiciones de servicio requeridas.
