Abstract

The unilateral contact of plates on elastic foundation is considered. Both vanishing and finite tensile contact (or adhesion) strength between the plate and the foundation are considered. The approach is used to study delamination due totransverse loads in two layer plates. The relationship with the brittle fracture mechanics approach is also discussed. Numerical results are presented to validate the present approach.

Sommario

Si esamina il problema di contatto di piastre su una fondazione elastica, costituita da molle caratterizzate da resistenza a trazione nulla o finita. Il secondo caso è usato per modellare l’adesione tra gli strati di piastre composite, ed è applicato allo studio della delaminazione di un pannello a due strati in presenza di forze trasversali. La formulazione proposta viene confrontata con il modello di frattura fragile, e vengono infime presentati alcuni risultati numerici.
