Rayleigh--Ritz Majorization Error Bounds of Mixed Type [PDF]

open access: greenSIAM Journal on Matrix Analysis and Applications, 2017
The absolute change in the Rayleigh quotient (RQ) for a Hermitian matrix with respect to vectors is bounded in terms of the norms of the residual vectors and the angle between vectors in [\doi{10.1137/120884468}]. We substitute multidimensional subspaces

Effect of Elastically Restrained Edges on Free Transverse Vibration of Functionally Graded Porous Rectangular Plate [PDF]

open access: yesMechanics 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
