      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 ...

      Minimum relative entropy criterion for damage detection and location 

      Kyprianou, Andreas; Mares, C.; Charalambous, Charalambos D.; Mottershead, J. E. (2007)
      Relative entropy has been employed, as an alternative to other regularization methods, in solving ill-conditioned linear inverse problems. Damage detection when treated as structural modification imparted by the damage ...

      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 ...
