This example shows how to apply the finite element method (FEM) to solve a Timoshenko beam problem, using both linear and quadratic basis functions for analysis. The Timoshenko beam theory is a 1-D problem that reduces the complex 3-D problem of beam deformation to a set of 1-D ...
Beam analogyA two-point boundary value problem for the optimal control of linear systems with a quadratic performance index is formulated and solved using the finite element method strategy. It is shown that the equations representing the optimality conditions for control are analogous to the ...
Tags Element Finite finite element Matrix Stiffness In summary, the size of the global stiffness matrix K (i.e., Kuu) for the 2-D problem is determined by the total number of nodes multiplied by the number of degrees of freedom for each node. In the solved problem, there are 12 nodes...
Professor O. C. Zienkiewicz, who was then on the faculty at Northwestern University. A few weeks after the presentation of the paper Zienkiewicz invited Clough to present a seminar on the finite element method to his students. Zienkiewicz was considered one ...

(ii) Two physical quantities with practical significance can be solved at the same time; thus, the computing cost is reduced. (iii) Compared with the finite element method, the space smoothness requirement is lower. In the future work, we can apply this method to other types of beam ...
The finite element (FE) method is capable of handling complex geometries and complex boundary conditions, as well as the transducer–structure coupling which occurs in smart structures. In a representative study, FE modelling was used to accurately predict the response of a cantilever beam ...
