The Uflyand-Mindlin theory of vibrating plates is an extension of Kirchhoff–Love plate theory that takes into account shear deformations through-the-thickness of a plate. The theory was proposed in 1948 by Yakov Solomonovich Uflyand (1916-1991) and in 1951 by Raymond Mindlin with Mindlin making reference to … See more Mindlin's theory was originally derived for isotropic plates using equilibrium considerations by Uflyand. A more general version of the theory based on energy considerations is discussed here. Assumed … See more For uniformly thick, homogeneous, and isotropic plates, the stress–strain relations in the plane of the plate are See more If we define the moment sum for Kirchhoff–Love theory as $${\displaystyle {\mathcal {M}}^{K}:=-D\nabla ^{2}w^{K}}$$ we can show that See more The canonical constitutive relations for shear deformation theories of isotropic plates can be expressed as See more • Bending • Bending of plates • Infinitesimal strain theory See more WebMay 21, 2024 · Simo ( 1985) developed a finite strain beam model which allows deformation of the beam in 3D space.
