Due to its excellent performance and high design freedom, the lattice structure has shown capabilities considerable potential in aerospace other fields. Inspired by bamboo structure, a cell configuration namely BCC4IZ is designed alternative layout obtained. Then, modeling method for non-uniform structures proposed. Four designs of landing footpad with different kinds cells are developed. A ser...

Recently, Kiriki, Nakano and Soma introduced a concept called pointwise emergence as new quantitative perspective into the study of non-existence averages for dynamical systems. In present paper, we consider set points with high systems non-uniform structure prove that this carries full topological pressure. For proof result, show such have ergodic measures arbitrary intermediate pressures.

In this paper, an efficient numerical scheme based on uniform Haar wavelets is used to solve the non-planar Burgers equation. The quasilinearization technique is used to conveniently handle the nonlinear terms in the non-planar Burgers equation. The basic idea of Haar wavelet collocation method is to convert the partial differential equation into a system of algebraic equations that involves a ...

In this paper, the buckling of non-homogeneous isotropic truncated conical shells under uniform lateral pressure and resting on a Winkler foundation is investigated. The basic relations and governing equations have been obtained for non-homogeneous truncated conical shells. The critical uniform lateral pressures of non-homogeneous isotropic truncated conical shells with or without a Winkler fou...

This research has been carried out to determine the marine propeller hydro-acoustic characteristics by Reynolds-Averaged Navier-Stokes (RANS) solver in both uniform and non-uniform wake flow at different operating conditions Wake flow can cause changes in pressure fluctuation and gas effect on propeller noise spectrum. Noise is generated by the induced trailing vortex wake and induced pressure ...
