Vibrations of L-Shaped Beam Structures With a Crack: Analytical Approach and Experimental Validation
Publikováno v:
Experimental Techniques. 40:1033-1043
A crack on a structural member introduces a local flexibility which is function of the crack depth. This new flexibility condition changes the dynamic behavior of the structure. The knowledge of the influence of the crack on the characteristic dynami

In the present paper the Differential Quadrature Method, DQM, and the domain decomposition are used to carry out the free transverse vibration analysis of non-uniform multi-span rotating Timoshenko beams with perfect and not perfect boundary conditio

The situation of structural elements supporting motors or engines attached to them is usual in technological applications. The operation of the machine may introduce severe dynamic stresses on the beam. It is important, then, to know the natural freq

The paper studies free transverse vibrations of axially functionally graded beams with stepped changes in geometry and in material properties. The differential quadrature method with domain decomposition technique is used. The governing equations of

This investigation arose from the practical necessity of placing a centrifugal pump rigidly attached to a thin, circular cover plate of a water tank in a medium size ocean vessel. Due to lack of space, it was necessary to locate the system off-center

The present work arose from the need of repairing steel plates badly damaged by corrosion in a portion of the structural element of the naval vehicle. The possibility of removing the portion and replacing it by a patch of a composite material was con
