Resumen
El cálculo de las uniones, como partes críticas en cualquier estructura, es complejo debido principalmente a la
interacción de varios elementos con diferentes materiales y geometrías. En Europa, dicho cálculo se rige por el
Eurocódigo 3, que establece métodos simplificados para cuantificar las propiedades de una unión de acero estructural. Lo
que queremos comprobar será cómo influye en el comportamiento de la unión el hecho de estar fabricada mediante
impresión 3D, puesto que el proceso de fabricación produce ortotropía en el material resultante.
Para este fin estudiaremos unas uniones de elementos estructurales, llamadas Tstub o T equivalente, fabricadas mediante
impresión 3D, tanto experimentalmente (empleando para ello el método de correlación digital de imágenes DIC, que
permite obtener mapas completos de deformación de diferentes superficies de la unión) como mediante simulaciones
numéricas (a través del método de los elementos finitos con el software Abaqus).
The calculation of the joints, as critical parts in any structure, is complex due mainly to the interaction of several elements with different materials and geometries. In Europe, this calculation is governed by Eurocode 3, which establishes simplified methods to quantify the properties of a structural steel joint. What we want to check will be how it influences the behavior of the union the fact of being manufactured by 3D printing, since the manufacturing process produces orthotropy in the resulting material. For this purpose we will study structural elements, called Tstub or T equivalente, manufactured by means of 3D printing, both experimentally (using the DIC digital image correlation method, which allows to obtain complete deformation maps of different surfaces of the union) as through numerical simulations (through the finite element method with the Abaqus software)
