TLDR
In this paper, a novel spectral transfer matrix for a cracked beam element is developed and the same matrix is used to identify the crack parameters on the beam structures, where the same spectral transfer matrices are used to detect the cracks in the beam elements.Abstract:

Assessment of NDT interferometric techniques for impact damage detection in composite laminates
TL;DR: In this article, the feasibility of using optical methods to detect impact damage in thin laminates is investigated and discussed, and the results obtained with the two techniques were compared with those acquired by a pulse-echo full-volume ultrasonic technique.

Identification of Crack Location in Vibrating Simply Supported Beams
TL;DR: In this paper, a cracked, simply supported uniform beam is treated for either bending or axial vibrations, and the crack is simulated by an equivalent spring connecting the two segments of the beam.

Simplified models for the location of cracks in beam structures using measured vibration data
TL;DR: In this paper, a new simplified approach to modeling cracks in beams undergoing transverse vibration is presented, which uses Euler-Bernoulli beam elements with small modifications to the local flexibility in the vicinity of cracks.

A finite element of a cracked prismatic beam for structural analysis
TL;DR: In this article, a finite element for the cracked prismatic beam is developed to evaluate the dynamic response of a cracked cantilever beam to harmonic point force excitation, which can be used in any appropriate matrix analysis of structures program.

An introduction to mechanical vibrations
TL;DR: In this paper, the authors describe a deterministic deterministic model for periodic motion in distributed systems. But they do not consider the effects of random and nonlinear Vibration.
