description This paper presents an experimental and numerical study of the effect of residual thermal stresses on the mechanical behavior of diagonally reinforced plates. The study focuses on the analysis of carbon/epoxy square plates onto which diagonal reinforcements were glued. These reinforcements were glued using two different methodologies: the first method was to glue the reinforcements at operating temperature (22 °C), while in the second methodology reinforcements were cured in an autoclave at 177 °C. Mechanical behavior assessment was based on the stiffness, free vibration, and buckling tests. For the study of the stiffness of the plates, an optical technique to determine the transversal displacement caused by the presence of a static load was employed. For the vibration tests, the natural frequencies associated with the first four modes of free vibration were determined by using a dynamic signal analyzer. For the linear and non-linear buckling, compression tests on a universal testing machine were performed, determining the displacements produced during the test using the digital image processing method. All experimental results were compared with results obtained from numerical approximations made with commercial software. The results show the effect of residual thermal stresses caused during the manufacturing process on the mechanical performance of diagonally reinforced plates.

Estos refuerzos fueron pegados siguiendo dos metodologías diferentes: la primera consistió en pegar los refuerzos a temperatura de servicio (22 °C), mientras que en la segunda, los refuerzos fueron curados en autoclave a temperatura de 177 °C. La evaluación del comportamiento mecánico se basó en la realización de ensayos de rigidez, vibración libre y pandeo. Para el estudio de la rigidez de las placas, se utilizó una técnica óptica que permite determinar de manera precisa los desplazamientos fuera del plano cuando una fuerza estática transversal es aplicada. Para los ensayos de vibración fueron determinadas las frecuencias naturales asociadas a los primeros cuatro modos de vibración libre mediante el uso de un analizador de señales dinámicos. Para los ensayos de pandeo, fueron realizados ensayos de compresión en una máquina universal de ensayos, determinando los desplazamientos producidos durante el ensayo por medio de un procedimiento de procesamiento digital de imágenes. Todos los resultados obtenidos experimentalmente fueron comparados con resultados logrados a partir de aproximaciones numéricas realizadas con software comercial. Los resultados muestran el efecto de las tensiones térmicas residuales que se originan durante la manufactura de las placas en el desempeño mecánico de placas reforzadas diagonalmente.application/pdfspaUniversidad Nacional de Colombia - Sede Bogotá - Facultad de Ingenieríahttps://revistas.unal.edu.co/index.php/ingeinv/article/view/60633Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónSanchez, Martha L. and Capote, Gil and Carrillo, Julián (2017) Experimental and numerical evaluation of the mechanical behavior of diagonally reinforced plates subjected to the effect of residual thermal stresses.
