... and their eigensolution or inversion can easily be performed. The effect of member changing the regular to a near‐regular structure can then be added. The purpose of this paper is to analyze near‐regular structures using the force method. Design/methodology/approach The paper uses the force method, and instead...

...A. Kaveh; M. Najimi Purpose This paper aims to study the variation theorems for pin‐jointed structures and rigid‐jointed frames. Design/methodology/approach The generalized force method is explained in a form to illustrate the parallelism of this method and the variation theorem approaches...

... of null vectors as far as it is possible and then algebraic method is utilized to find the complementary part of the null basis. Originality/value This hybrid approach makes the use of pure force method in the finite element analysis feasible. Here, a simplified version of the algorithm is also...

...Burkhard Göttlicher; Karl Schweizerhof The computation of structures moving in central force fields generally requires long‐time integration including geometrically nonlinear behavior (large rotations) as such, e.g. satellite structures move for a long time. To achieve a numerically stable...

...Xiang Cui An algorithm for the visualization of the electric force lines is discussed. Based on the nodal potentials calculated by the conventional finite element method, the boundary conditions of the electric flux are determined by the integral of the electric displacement along all conductors...
