In many different industries, such as chemical industry, plastic industry and especially in rubber industry, there are systems with random parameters. It is well-known in case of the systems with determined parameters that the systems can be either stable or unstable. But, in case of the random parameters the systems can be stable, unstable, or stable with some probability. The stability proble...

The internal pressure of a thin-walled cylindrical structure under axial compression may improve the buckling stability by relieving loads and reducing initial imperfections. In this study, effect on knockdown factor is investigated for axially compressed composite cylinders with different shell thickness ratios slenderness ratios. Various are considered when derived both pressure. Nonlinear po...

Metasurfaces, the planar version of artificial structured media at sub-wavelength scale, provide ability to manipulate light wave in a naturally unavailable way. They offer an unprecedented platform for plethora applications ranging from holography, imaging, optical communication nonlinear source and quantum computing. Conventionally straightforwardly, metasurfaces are prepared ordered configur...

Snap-through instability of viscoelastic materials is known to generate novel behavior, featured as pseudo-bistability, i.e. the capability a system in maintaining deformed configuration for certain period time after removal an external load, followed by snapping back its initial automatically, due combination time-dependent mechanical property and geometric nonlinearity system. This work numer...
