Influence of joint flexibility on buckling analysis of free–free beams

Abstract In this work, an application of two noded beam finite element methodology, which is demonstrated in the previous research work for vibration analysis with a flexible joint problem, has been further extended here to investigate buckling behaviour free–free subjected in-plane compressive load. Joint modelled as rotational spring, where spring stiffness governs joint. Variation first five non-dimensional loads reference location well parameters are briefly presented. It understood that looseness can significantly influence and plays important role accurately determining jointed beams loads.
