It is found that the initial stress, geometric imperfection and volume fraction index greatly change the behavior of nonlinear vibration.
The numerical results also show the dominant effect of constituent volume fraction index on the dispersion of dynamic characteristics.
The effects of aspect ratio, volume fraction index on the critical loads and temperatures are also considered.
Finally, the influences of temperature, moisture concentration, aspect ratio and volume fraction index of the model are investigated in detail.
Also, the effect of individual constituent materials and volume fraction index are investigated while the relative standard deviation changes.
Finally, influences of shear stresses, volume fraction index and shell characteristics on the critical lateral and hydrostatic pressures are investigated.
The effects of volume fraction index, core thickness and temperature gradient on natural frequencies of FGM sandwich shells are investigated.
Parametric studies are conducted for two configurations, different volume fraction index and different geometrical parameters of FGM sandwich truncated cones.
In contrast, the effect of volume fraction index N becomes weaker when the plate is supported by an elastic foundation.
Moreover, many important parametric studies of stringers, temperature field, material volume fraction index, the thickness of metal layer, etc. are taken into investigation.
In contrast, the nonlinear frequency ratio decreases in both the pre- and post-buckling region on increasing the volume fraction index.
