Effect of Elastically Restrained Edges on Free Transverse Vibration of Functionally Graded Porous Rectangular Plate [PDF]
Mechanics of Advanced Composite Structures, 2022 In this paper, the author studied free transverse vibration of a thin isotropic simply-supported functionally graded (FG) rectangular plate with porosity effect based on classical plate theory. The plate is considered to be elastically restrained against

Inverse-designed gyrotropic scatterers for non-reciprocal analog computing. [PDF]
NanophotonicsAbstract While conventional von Neumann based machines are increasingly challenged by modern day requirements, electromagnetic analog computing devices promise to provide a platform that is highly parallel, efficient and fast. Along this paradigm, it has been shown that arrays of subwavelength electromagnetic scatterers can be used as solvers of ...

Generalized stress field in granular soils heap with Rayleigh–Ritz method
Journal of Rock Mechanics and Geotechnical Engineering, 2017 The stress field in granular soils heap (including piled coal) will have a non-negligible impact on the settlement of the underlying soils. It is usually obtained by measurements and numerical simulations.
