Popis:	U radu je istaknuto da je postupak modeliranja i predviđanja čvrstoće vlaknima ojačanih polimernih laminata, zbog njihove anizotropije vrlo složen. Teškoće su osobito izražene u predviđanju ekvivalentnog naprezanja, odnosno čvrstoće laminata pri složenom opterećenju. Prikazan je model određivanja čvrstoće pri složenom opterećenju staklenim vlaknima ojačanog polimera. Postupak je moguće primijeniti za proračun čvrstoće polimernih laminata, bez obzira na vrstu matrice i vlakna. It is emphasized that the modelling of fibre-reinforced polymer laminates, and prediction of their strength, is a highly complex task namely because of their anisotropy. Difficulties are especially pronounced in the prediction of equivalent stress, i.e. the strength of laminate when subjected to complex load. The model for defining the strength of glass-fibre reinforced polymers subjected to complex load is presented. The procedure can be applied in the analysis of strength of polymer laminates, regardless of the type of matrix and fibre.
