Webthe Kirchhoff-Love and Reissner-Mindlin theories for linearly elastic plates, in a variety of ways, which have been classified under two general categories, standard [60, 61]and improved [59].2 For nonlinear elastic plates, standard Γ-convergence clashed with the Kirchhoff-Love hypothesis. WebThe Uflyand-Mindlin theory is used to calculate the deformationsand stressesin a plate whose thickness is of the order of one tenth the planar dimensions while the Kirchhoff–Love theory is applicable to thinner plates. The form of Uflyand-Mindlin plate theory that is most commonly used is actually due to Mindlin.
