Resumen
In the present study, bending analysis of the functionally graded (FG) with spatial coordinates cylindrical nanoshells in a thermal environment is studied for the first time. The mechanical properties of the cylindrical nanoshells including modulus of elasticity and thermal expansion coefficient are assumed to be changed along the length, width, and thickness directions, which can change based on an arbitrary function. In addition, it is assumed that the mechanical properties of the shell are temperature-dependent. First-order shear deformation theory (FSDT) is applied to consider the shear effects of the moderately thick cylindrical shells. Nonlocal elasticity theory is used to investigate the small-scale effect. Galerkin solution method is applied to obtain the deflection of the 3D-FG cylindrical nanoshells with simply-supported boundary conditions. The impact of several parameters including temperature variation and FG indexes are investigated on the deflection of the 3D-FG cylindrical nanoshells. The simulation indicates that when the variation of the temperature is greater/smaller than 100 K, the impacts of the temperature variation and FG indexes on the deflection of the 3D-FG cylindrical nanoshells increase/decrease.
