Holes, inserts, free edges and ply drops

Concentrated loads and geometric discontinuities need gradual load transfer and local containment of splitting and delamination.

In simple terms

Concentrated loads and geometric discontinuities need gradual load transfer and local containment of splitting and delamination.

Fasteners, inserts, hard points, thickness transitions and trimmed edges.

Surface woven or +/-45 degree plies may help containment but never replace bearing, bypass, pull-through and interlaminar analysis.

Bolted joints, potted inserts, brackets and panel edges.
