Development of the calculation of composite plate structures, with circular or elliptical cutouts


Development of the calculation of composite plate structures, with circular or elliptical cutouts


FIDAMC has published a scientific article in the journal of Composite Structures. The article is focused on the development of an innovative methodology for the calculation of composite plate structures, with circular or elliptical cutouts, considering variable thickness and stacking sequence. In addition, it makes possible to introduce local reinforcements. The research has been carried out in collaboration with the Universidad de Sevilla. The article is available at the following link.

ABSTRACT

This study aims to develop a closed-form methodology for estimating the resultant forces in a finite composite plate, weakened by the presence of elliptical cutouts, under membrane loads. Following an innovative approach, the developed methodology can deal, in the presence of cutouts, with a non-uniform lay-up distribution in the plate. To this end, different laminate features, including the stacking sequence, thickness, and even local reinforcements, will be considered as variable inputs. The main motivation behind this research is to increase the range of applicability of the closed-form methodologies devoted to the structural analysis of composite plates with cutouts, with the purpose of using the present methodology in the first phases of component design.
