The effect of using thin plies to increase the bearing strength composite laminates has been investigated. A series 5 theoretically identical stiffness with varying proportions were manufactured a single material system. Four specimens from each plate tested for and damage was subsequently characterized an optical microscope. results show that performance in terms stiffness, at onset damage, ul...

Crystals with anisotropic thermoelectric transport coefficients can yield a high figure-of-merit along the direction highest electronic mobility, provided Seebeck coefficient and thermal conductivity are relatively isotropic. In this study, we combine experiment theory to investigate properties of quasi-1D Zintl phase Ca5In2Sb6. Ca5In2Sb6 is predicted by ab initio calculations have extremely p-...

We introduce new design method for 3D isotropic transformation optics device using smart transformation optics. In 2 dimension smart transformation optics, elastic deformation satisfied quasi-conformal transformation with negative Poisson’s ratio -1. We extended smart transformation optics to 3 dimension and demonstrated 3D isotropic metamaterials waveguide. This 3D waveguide is arbitrary benda...

Dimensional crossover in the Kondo necklace model is analyzed using the bond-operator method at zero and finite temperatures. Explicit relations describing quasi-two-dimensional properties are obtained by asymptotically solving the resulting equations. The crossover from two dimensions (2d) to three dimensions (3d) is investigated, turning on the electronic hopping ([Formula: see text]) of cond...

The first-arrival quasi-P wave travel-time field in an anisotropic elastic solid solves a first-order nonlinear partial differential equation, the qP eikonal equation, which is a stationary Hamilton–Jacobi equation. The solution of the paraxial quasi-P eikonal equation, an evolution Hamilton–Jacobi equation in depth, gives the first-arrival travel time along downward propagating rays. We devise...
