DESCRIPTION:Title:\n\nModal Analysis of One Dimensional Structures Prone to
  Unilateral Contact Conditions\n\nAbstract: \n\nThe prediction of resonanc
 e in vibrating structures is a subject of importance in the field of mecha
 nical engineering and is useful for structural health as well as for estim
 ating the capabilities of vibrating structures. While classical modal anal
 ysis for linear systems relies on eigenvalue analysis\, nonlinear dynamica
 l systems lack superposition and the notion of modes of vibration has been
  extended to the concept of nonlinear normal modes which are seen as one-p
 arameter continuous families of periodic motions of the investigated syste
 m. It is known that nonlinear normal modes feature energy-dependent natura
 l frequencies. The presentation will focus on a subclass of mechanical sys
 tems where the nonlinearity stems from unilateral contact and frictional o
 ccurrences. Formulation\, solution methods and solutions will be presented
  on a one-dimensional bar example.\n
