The energy dissipation due to the failure of composites is of particular interest for crash applications involving dynamic loading. Separation of layers or delamination which can occur in opening (mode-I) is one of the key ...

A repair technique involving the containment of local bending of sandwich facesheet by strategically filling honeycomb core cells has been explored to improve the damage tolerance of impact damaged sandwich panels. The ...

Data obtained from digital flight data recorders installed on a fleet of 27 Beech 1900D airliners are used to assess the actual operational environment of propellers on commuter aircraft. The data consists of 910 complete ...

The adhesively bonded layered aluminum is used in aircraft structures to avoid knife edge situations when flush head fasteners are used with minimum gage skins. A 3-D finite element model was used to estimate the location ...

A study has been made of flat plate chamfer-based, crush trigger mechanisms subjected to axial compression, for use with energy-absorbing Fiber reinforced composites. This paper will focus on the trigger mechanisms in flat ...
