Delamination

delamination

[dē‚lam·ə′nā·shən]
(biology)
The separation of cells into layers.
(embryology)
Gastrulation in which the endodermal layer splits off from the inner surface of the blastoderm and the space between this layer and the yolk represents the archenteron.
(engineering)
Separation of a laminate into its constituent layers.

Delamination

Coming apart layer by layer; as in a separation of plies in a plywood panel, either through failure of the adhesive or through failure at the interface of the adhesive and the lamination.

delamination

A failure in a laminated structure characterized by the separation or loss of adhesion between plies, as in built-up roofing or glue-laminated timber.
