...L.-X. Li; J.-S. Sun; H. Sakamoto A generalized infinite element is presented by combining following aspects: (1) The geometry mapping in the Cartesian system is chosen so as to facilitate the generation of infinite element mesh; (2) The decay variable is defined as the in situ major axis...

...-pinned beams. The changes in the transverse vibration and associated eigenfrequencies of the beams are considered. Specifically, a complete variational beam vibration model is developed and presented that allows variations in geometry and material properties to be considered, with and without crack...

... ¯ The ability to modify the geometry may lead to nonrealizable dimensions e.g. negative thickens or dimensions that cannot be realized. For a beam whose thickness depend on the sought parameter-vector we obtain: (3) h _ ⩽ h θ ⩽ h ¯ where h θ , h _ , h ¯ are here the working...
