Skin-core debonding in sandwich structures, Other Engineering

Assignment Help:

If the skins are peeled from the core, a sandwich structure loses its strength and stiffness.

This can occur under

- wave-slamming in fast ferries
- rapid depressurisation of an aircraft

The single cantilever beam (SCB) is used for thick-skinned structures.

The lower skin is loaded forcing a crack along the skin-core interface. The force-displacement (P-δ) curve and crack lengths, a, are recorded The compliance, C, is assumed to follow:

Typical values:

Glass fibre epoxy/balsa 900 J/m2

Carbon fibre/PVC foam 2000 J/m2
