The theory of superimposed incremental elastic deformations is applied to a deformed configuration residually-stressed circular cylindrical tube. tube subject internal or external pressure and an axial load that maintain its shape, then bifurcations from this shape are analysed. Detailed governing equations boundary conditions provided for axisymmetric, prismatic asymmetric general form strain–...

Origami structures enrich the field of mechanical metamaterials with the ability to convert morphologically and systematically between two-dimensional (2D) thin sheets and three-dimensional (3D) spatial structures. In this study, an in-plane design method is proposed to approximate curved surfaces of interest with generalized Miura-ori units. Using this method, two combination types of crease l...

In this study, the small scale effect on the linear free-field vibration of a nano-circular plate has been investigated using nonlocal elasticity theory. The formulation is based on the classical theory and the linear strain in cylindrical coordinates. To take into account the small scale and the linear geometric effects, the governing differential equation based on the nonlocal elasticity theo...
