The evolution of the gas distribution on a given pipe is modeled by an isothermal semilinear compressible Euler system in one space dimension. On the network, solutions satisfying (at nodes) the so called Kirchhoff flux …

WebThe Kirchhoff model describes the statics and dynamics of thin rods within the approximations of the linear elasticity theory. In this paper we develop a method, based … 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 proposed by … 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 … 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.
