Behavior of indented sandwiches structure with Nomex honeycomb core and metallic skins subjected to compressive loading (CAI)

Behavior of indented sandwiches structure with Nomex honeycomb core and metallic skins subjected to compressive loading (CAI)

A finite element model is proposed to determine the residual strength and the evolution of damage area of indented sandwiches structures with Nomex honeycomb core and metallic skins indented by a spherical indenter under longitudinal compression load (CAI). The honeycomb is represented by a grid of...
