Original abstract
A finite-element model has been developed to study buckling and postbuckling behaviour of a square plate made of fibre-metal laminate with either one or two delaminations. A study into the effect of different ply orientations and different through-the-thickness positions of delaminations upon the buckling load and load-bearing capability of buckled plates was performed. The results indicate significant reduction of buckling loads for plates with near-surface delamination and certain ply angles.

Příspěvek se zabývá analýzou chování stlačované čtvercové desky s jednou či dvěma kruhovými delaminacemi. Pomocí výpočtových simulací byl zkoumán vliv orientace vrstev laminátu a pozice delaminací po tloušťce desky na velikost zatížení při ztrátě stability desky a na její únosnost. Výsledky naznačují, že v případě delaminací ležících blízko povrchu desky a pro určité orientace vrstev laminátu dochází k významnému snížení zatížení při ztrátě stability desky.
