Resumen

Un análisis multi-criterio ha sido desarrollado para evaluar la capacidad de absorción de energía de tubos circulares fabricados con láminas de metal expandido y láminas sólidas. Mediante un Proceso de Jerarquía Analítica (AHP - Analytic Hierarchy Process) se asignaron de peso a diferentes parámetros de carga y resistencia de impacto. Posteriormente, estos pesos han sido luego atribuidos a una Evaluación Proporcional Compleja (COPRAS - Complex Proportional Assessment) para seleccionar la mejor opción entre seis alternativas disponibles. Los resultados muestran que los tubos circulares fabricados con láminas de metal expandido y celdas individuales con orientación α=0º presentan características favorables para absorber energía de forma controlada y estable así como eficientes parámetros de diseño estructural. La metodología de análisis multi-criterio constituye una valiosa herramienta en los procesos de toma de decisiones para la selección de dispositivos empleados en aplicaciones de absorción de energía.
