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.

Or a PEM might have no significant warping, but may show internal anomalies such as cracks, voids or delaminations.
Not all of these delaminations resulted in immediate electrical failures, probably because humidity testing puts little mechanical load on the assemblies.
The infrared and video data collected for each of the 11 decks was analyzed to quantify and map overlay debonding, rebar-level delamination, patching, and spalling.
