In-Plane Free Vibration of Two-Member Open Frame with Transverse Crack with End Mass

This paper focus on addressing the problem of0In-plane free vibration analysis0of two-member open0frame with transverse0crack. A two-member0open frame is0modelled using0Euler-Bernoulli beam0theory. The angle between the beams is 900 and payload is attached at the end0of the second0beam. The0linearized equation of0motion is derived using0Hamilton's principle0and the0general frequency equations are presented with crack with two member open frame. Transverse vibration0of a frame in the0presence of a normal edge0crack is considered. The crack is modelled using the concept of rotational spring. The determination0of natural frequencies0for a given crack0location and0size is a straightforward problem and is the aim0of project work. Numerical results are tabulated for both the cases (i,e without and with end mass) and graphs are drawn.
