Abstract :
In this paper, the thermo-mechanical buckling analysis of a non-homogeneous
open cylindrical shell reinforced with single-walled carbon nanotubes with a
uniform/non-uniform distribution on an elastic foundation under thermal and
mechanical loads has been addressed. Using the minimum energy principle,
the governing differential equations of this system are derived and in order
to determine the properties of the reinforced composite shell, the modified
mixtures law has been used. It is assumed that the properties of single-walled
carbon nanotubes are acquired from molecular dynamics simulation. It is
also assumed that the material properties of the reinforced carbon nanotube
composites are linear in the thickness and are defined based on mixture law
via a micro-mechanical model in which the nanotube performance parameter
is considered. After solving these equations, the effects of geometric characteristics
of the shell and material properties on the critical load and critical
temperature of shell buckling are investigated.
