The flexible crashworthy structure can significantly mitigate the ship impact force on bridge pile.This paper establishes an analytical model to obtain the equivalent elastic stiffness of the structure.The model is composed of a closed circular beam connected to the circular foundation with distributed ...

After an extensive study of the relevant entities the above principle is successfully applied to the derivation of the geometrical stiffness of a beam element in space. The consistency of the present approach is demonstrated by the full agreement with the prior results of the authors based on the...
It is shown that, if Poisson's ratio ν is constant, the stiffnesses of a beam may be computed from formulae derived from the classical theory of plane sections, though the local deformations need not generally coincide. If ν≠ const the stiffnesses differ from their classical values. Two...
A method for calculating the dynamic transfer and stiffness matrices for a straight Timoshenko shear beam is presented. The method is applicable to beams with arbitrarily shaped cross sections and places no restrictions on the orientation of the element coordinate system axes in the plane of the cro...
The general aim of the investigation described in this report is the achievement of efficient design in wing beams. The purpose of the tests was to determine factors to apply to the usual beam formula in order that the properties of wood based on tests of rectangular sections might be used ...
The finite element equation for the coupled beam vibrations reads (Senjanović and Grubišić, 1991):{PR}=[kbkt]{UV}+[mbmbtmtbmt]{U¨V¨}- Asymmetry analysis of restoring stiffness By observing formulae (30) for restoring coefficients due to bending, it is obvious that the restoring ma...
Christoph Hahn, technical education specialist at MathWorks, introduces you to an efficient approach to determine structural properties of a steel tube frame using the direct stiffness method. Determining the structural properties of a truss or beam framework is part of many introductory mechanics ...
After almost twenty years of intense work on the celebrated LaAlO3/SrTiO3system, the recent discovery of a superconducting two-dimensional electron gas (2-DEG) in (111)-oriented KTaO3-based heterostructures injects new momentum to the field of oxides interface. However, while both interfaces shar...
