In this paper, free vibration of carbon nanotube-reinforced functionally graded circular plates with hole has been investigated. Distribution of carbon nanotubes are continuous and the gradual and graded changes of materials through the plate thickness are considered as volume fraction. Considering the linear and non-linear variation of circular plates through the radial direction and also c...

Unsymmetrical buckling of nonuniform circular plates with elastically restrained edge and subjected to normal pressure is studied in this paper. The asymmetric part the solution sought terms multiples harmonics angular coordinate. A numerical method employed obtain lowest load value at which waves circumferential direction can appear. effect material heterogeneity boundary on examined. For a pl...

The problems of optimal design metal structures are usually formulated as the problem finding such values selected parameters that provide smallest (or largest) value optimality criterion in area admissible solutions. In most works on optimization structures, parametric considered, limited by preliminary assignment a constructive form with possibility changing its parameters. To solve these pro...
