The Reissner theory is slightly different and is a static counterpart of the Uflyand-Mindlin theory. Both theories include in-plane shear strains and both are extensions of Kirchhoff–Love plate theory incorporating first-order shear effects. See more 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 … 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 … 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 • Linear elasticity • Plate theory • Stress (mechanics) 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 $${\displaystyle {\mathcal {M}}^{K}:=-D\nabla ^{2}w^{K}}$$ See more WebMax Erich (Eric) Reissner (January 5, 1913 – November 1, 1996) was a German-American civil engineer and mathematician, and Professor of Mathematics at the Massachusetts … tri for hospice

WebIn this study, a dynamic Mindlin–Reissner-type plate is developed based on a simplified version of Mindlin’s form-II first-strain gradient elasticity theory. The governing equations of motion and the corresponding boundary conditions are derived using the general virtual work variational principle. The presented model contains, apart from the two classical … WebOne of those theories is based on the assumption that the fibers across the thickness remain straight after deformation, but not perpendicular to the reference surface. This is the Mindlin–Reissner shell theory, which is a direct extension of the Timoshenko beam theory in plates and shells.
