Determinación de la resistencia a esfuerzo cortante en ensayos de flexión a paneles sándwich PUR: análisis de las dificultades y simulación por elementos finitos

Abstract

La utilización de elementos constructivos compuestos, combinando distintos materiales con características complementarias, se ha extendido cada vez más. Los paneles sándwich, compuestos por capas externas de metal que les aporta resistencia y núcleo de espuma aislante térmica, que proporciona cualidades que mejoran el confort térmico en el interior de todo tipo de construcciones, se utilizan en cerramientos y cubiertas que conforman la envolvente de los edificios. De los distintos controles de calidad a que se han de someter, en este artículo se propone una mejora al indicado en las normas para la determinación de la resistencia al esfuerzo cortante, consiguiendo evitar muchos resultados anómalos obtenidos por la utilización de placas rígidas en los apoyos. Finalmente, tanto el problema observado como la solución propuesta, se modelizan y simulan mediante el método de elementos finitos.
