Assignment of natural frequencies by an added mass and one or more springs
Kyprianou, Andreas; Mottershead, J. E.; Ouyang, H. (2004)The problem of assigning natural frequencies to a multi-degree-of-freedom undamped system by an added mass connected by one or more springs is addressed. The added mass and stiffnesses are determined using receptances from ...

Estimation of rotational frequency responses
Mottershead, J. E.; Kyprianou, Andreas; Ouyang, H. (2003)Rotational frequency response functions are potentially valuable for structural damage detection but are difficult to obtain because of the practical problems of applying a pure moment. In the literature various indirect ...

Modelling and Simulation of Bolted Joints under Harmonic Excitation
Oldfield, M.; Ouyang, H.; Mottershead, J. E.; Kyprianou, Andreas (2003)Bolted metal joints under harmonic loading exhibit hysteretic behaviour. This is the major source of damping in frame structures with bolted joints, since the material damping of these structures is very small. In this ...

Structural modification. Part 1: Rotational receptances
Mottershead, J. E.; Kyprianou, Andreas; Ouyang, H. (2005)The inverse problem of assigning natural frequencies and antiresonances by a modification to the stiffness, mass and damping of a structure is addressed. Very simple modifications such as the addition of masses and grounded ...

Structural modification. Part 2: Assignment of natural frequencies and antiresonances by an added beam
Kyprianou, Andreas; Mottershead, J. E.; Ouyang, H. (2005)In this paper the inverse structural modification problem is solved in order to determine the dimensions of the cross-section of a beam that when added to an original structure will assign natural frequencies or antiresonances ...
