Abstract:
A novel foldable model is used for extending the constitutive relations of a cylindrical pressure vessel composed of the copper matrix cylinders reinforced with three-dimensional nanofillers named as graphene origami. Deformability is accounted based on the shear deformable kinematic model using the first order shear deformation theory. The overall material characteristics are evaluated using the Halpin-Tsai micromechanical models and rule of mixture. The governing equations are derived using the virtual work principle. Nanofiller characteristics dependent results are obtained using the analytical method. The results show an enhancement in the deformation and stress components with an enhancement in the foldability parameter and thermal loads as well as decrease in volume fraction.

The process begins by slicing the tube at critical points and analyzing the internal forces and stress components at these sections, focusing on the centroid. Normal stresses, generated by axial forces and bending moments, are either compressive or tensile and vary across the section from...
