Reissner–mindlin theory
WebNonlinear Theory of Elastic Plates provides the theoretical materials necessary for the three plate models-Cosserat plates, Reissner-Mindlin plates and Kirchhoff-Love plates- in the context of finite elastic deformations. 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 where See more If we define the moment sum for Kirchhoff–Love theory as $${\displaystyle {\mathcal {M}}^{K}:=-D\nabla ^{2}w^{K}}$$ See more The canonical constitutive relations for shear deformation theories of isotropic plates can be expressed as Note that the plate thickness is $${\displaystyle h}$$ (and not $${\displaystyle 2h}$$) … See more • Bending • Bending of plates • Infinitesimal strain theory • Linear elasticity • Plate theory • Stress (mechanics) See more

WebApr 6, 2024 · Abstract. The formulation used by the most of studies on elastic torus are either Reissner’s mixed formulation or Novozhilov’s complex-form one; however, for vibration and some displacement boundary-related problem of torus, those formulations face a great challenge. It is highly demanded to have a displacement-type formulation for …
