摘要：

Strips cut from sandwich panels with glass-fibre-reinforced plastic skins and poly(vinyl chloride) foam cores were supported on a rigid base and indented at mid-length with a cylindrical indenter. Load/deflection characteristics are presented for a range of skin thicknesses, core thicknesses, core densities, specimen lengths and indenter radii. Theory which models the top skin as a linear elastic beam and the core as an elastic-plastic foundation is used, successfully, to predict the loads at which the core yields and the top skin fails.
