Abstract:
Numerical and experimental studies have been conducted to investigate the effect
of reinforcements around cutouts on the stress concentration and buckling
behaviour of a carbon/epoxy composite panel under in-plane shear load. Four
different types of cutout reinforcements made of a range of materials were
evaluated. In the analysis, finite element method and an analytical method based
on the laminate theory were employed to perform parametric studies on the
various reinforcement designs. Four test panels were then manufactured and
tested to validate the analysis results. Good agreement was found between the
analytical and test results. Based on the validated analytical models, the best
cutout reinforcement was determined.
