Abstract

This paper presents the state of the art of modeling and detection of damages in metallic and composite structures. The continuous, discrete-continuous, and discrete models available in the literature are described. Also, the influence of damages on vibration behavior of structures is presented, along with possibilities of damage detection based on changes in dynamic characteristics of structures.

Keywords:

  • damage modeling;
  • fatigue crack;
  • delamination of layers;
  • isotropic and composite materials
