Mechanical behavior and failure of sandwich structures
The failure behavior of composite sandwich beams under three- and four-point bending was studied. The beams were made of unidirectional carbon/epoxy facings and various core materials including PVC closed-cell foams, a polyurethane foam and an aluminum honeycomb. Various failure modes including fa...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | The failure behavior of composite sandwich beams under three- and four-point bending was studied. The beams were
made of unidirectional carbon/epoxy facings and various core materials including PVC closed-cell foams, a polyurethane
foam and an aluminum honeycomb. Various failure modes including facing wrinkling, indentation failure and core
failure were observed and compared with analytical predictions. It was established that the initiation, propagation and
interaction of failure modes depend on the type of loading, constituent material properties and geometrical dimensions. |
