Abstract

The low out of plane strength of co-cured joint has been a topic of research for improving the strength of co-cured composite structures. The cutouts made in the composite interspar ribs of wing and frames of fuselage of aircraft structure are the zone of peak peel load (PPL) leading to further weakening of the co-cured joint. A green analytical study is carried out to explore the nearly optimal geometrical shape of stringer cutout that can redistribute the peel load (RPL) to a minimum possible value. SAGAR PLot: The physical phenomenon seen in the river meandering before joining the Sea, SAGAR, is selected to explain the analytical figures to identify the optimal geometrical shape of stringer cutout. Had the concept of SAGAR PLot not been impersonated in the present analytical study, the study would have yielded the unrealistic solution of no material-no stress by making larger and larger size of stringer cutouts.
