Analysis of Euler-Bernoulli beam with Galerkin methods
Abstract:On the basis of Euler?Bernoulli beam theory and Galerkin methods, the paper derives a solution and equation for the Euler?Bernoulli beam's problem, whose conclusion is the base and convenient for the relative FEM numeric computations and the programme developing.
