A large space antenna structure will inevitably vibrate due to the space thermal environment
and maneuver actions of the satellite. Such vibration will last continuously and affect normal …

Delamination is one of the detrimental defects in laminated composite materials that often
arose due to manufacturing defects or in-service loadings (eg, low/high velocity impacts) …

The present paper introduces mixed unified particle swarm optimization (MUPSO) algorithm
to detect and quantify the delamination damages in composite beams and plates using …

Delamination damage is one of the most critical damage modes of composite materials. It
takes place through the thickness of the laminated composites and does not show subtle …
