| Term (EN) | geometrically nonlinear elastic analysis with imperfections included (GNIA) |
|---|
| Definition (EN) | An analysis with imperfections explicitly included, similar to a GNA analysis as defined in 1.3.5.5, but adopting a model for the geometry of the structure that includes the imperfect shape (i.e. the geometry of the middle surface includes unintended deviations from the ideal shape). The imperfection may also cover the effects of deviations in boundary conditions and / or the effects of residual stresses. A bifurcation eigenvalue check is included at each load level. |

| Term (SR) | geometrijski nelinearna elastična analiza s uključenim imperfekcijama (GNIA) |
|---|
| Definition (SR) | Analiza u kojoj su imperfekcije eksplicitno uključene, slična GNA analizi definisanoj u 1.3.5.5, ali koja usvaja geometrijski model konstrukcije koji uključuje nesavršeni oblik (npr. geometrija srednje površine uključuje slučajna odstupanja od idealnog oblika). Imperfekcija takođe može da pokrije efekte odstupanja u konturnim uslovima i/ili efekte rezidualnih napona. Provjera bifurkacione sopstvene vrijednosti se vrši sa svakim nivoom opterećenja. |
