Kirchhoff beam theory
The Kirchhoff–Love theory of plates is a two-dimensional mathematical model that is used to determine the stresses and deformations in thin plates subjected to forces and moments. This theory is an extension of Euler-Bernoulli beam theory and was developed in 1888 by Love using assumptions … Meer weergeven Let the position vector of a point in the undeformed plate be $${\displaystyle \mathbf {x} }$$. Then The vectors $${\displaystyle {\boldsymbol {e}}_{i}}$$ Meer weergeven The original theory developed by Love was valid for infinitesimal strains and rotations. The theory was extended by von Kármán to situations where moderate rotations could be expected. Strain-displacement relations For the … Meer weergeven • Bending • Bending of plates • Infinitesimal strain theory • Linear elasticity Meer weergeven For an isotropic and homogeneous plate, the stress-strain relations are where $${\displaystyle \nu }$$ is Poisson's Ratio Meer weergeven The dynamic theory of thin plates determines the propagation of waves in the plates, and the study of standing waves and vibration modes.
