Estimation of stress concentration due to defects in a honeycomb core

•A technique by replacing defects with an elliptical hole was proposed.•Our predicted values of stress concentration agreed with numerical results.•Our predicted values of moment concentration agreed with numerical results. One of the authors has investigated the stress concentration in honeycomb co...
