DESARROLLO Y EXPERIMENTACIÓN NUMÉRICA DE COMPORTAMIENTO MECÁNICO DE ESTRUCTURAS CELULARES FG (DEVELOPMENT AND NUMERICAL EXPERIMENTATION OF MECHANICAL BEHAVIOR OF CELLULAR STRUCTURES FG)
Resumen
Dada la importancia de mitigación de energía en varias áreas de la industria, las estructuras ligeras que atenúen cargas de impacto han sido el foco de interés en años recientes. Una de ellas es la estructura celular hexagonales o honeycomb. Estas, pueden fabricarse como estructuras celulares funcionalmente graduadas (FG) que representan un tipo novedoso de materiales, donde variaciones en tamaño de celda, forma, espesor de pared, o de material produce una variación funcional en la densidad relativa de la estructura.
Con la finalidad de diseñar estructuras ligeras que atenúen cargas de impacto, en este trabajo se realizará un estudio para explorar la posibilidad de fabricar un material celular funcionalmente graduado (FG), el cual se generará al introducir un gradiente de composición de dos materiales diferentes y se analizará numéricamente en términos de su respuesta mecánica con el fin de determinar la potencialidad de su uso como atenuador de cargas de impacto.
Palabra(s) Clave: Comportamiento mecánico, estructuras, funcionalmente graduado, material celular.
Abstract
Given the importance of energy mitigation in several areas of industry, lightweight structures that mitigate impact loads have been the focus of interest in recent years. One of them is the hexagonal or honeycomb cellular structure. These can be manufactured as functionally graded cell structures (FG) that represent a novel type of material, where variations in cell size, shape, wall thickness, or material produces a functional variation in the relative density of the structure.
With the purpose of designing light structures that attenuate impact loads, in this work a study will be carried out to explore the possibility of manufacturing a functionally graduated cellular material (FG), which will be generated by introducing a gradient of composition of two different materials and it will be analyzed numerically in terms of its mechanical response in order to determine the potentiality of its use as an impact load attenuator.
Keywords: Cellular material, functionally graded, mechanical behavior, structures.
