Crack identification and characterization in beams by nonlinear vibration analysis
The slight nonlinear character of a vibrating cracked beam is exploited for the purpose of determining crack location, crack depth, and crack-opening load. The approach is motivated by examining the response of a bilinear spring-mass system to excitation at two frequencies, such that the sum or …

Analysis by Meshless Local Petrov-Galerkin Method of Material Discontinuities, Pull-in Instability in MEMS, Vibrations of Cracked Beams, and Finite Deformations of Rubberlike Materials
… and forced vibrations of a segmented bar and a cracked beam, pull-in instability of an electrostatically actuated microbeam, and plane strain deformations of incompressible hyperelastic materials. The Moving Least Squares (MLS) approximation is used to generate basis functions for the trial …

Model-Based Vibration Diagnostic of Cracked Beams in the Time Domain
… model for the transverse vibrations of beams consisting of partial differential equations of motion with varying coefficients to account for the presence of damage. In order to provide accurate representation of the structure's behavior over a broader frequency range, a new continuous …

Probabilistic Analysis of a Thin-walled Beam with a Crack
… The damaged wing is modeled by a thin-walled beam with a longitudinal crack the response of which can be obtained analytically. As uncertainties are present in the location and size of the crack as well as in the applied loads, their effects are incorporated into the framework consisting of …

Vibration- and Impedance-based Structural Health Monitoring Applications and Thermal Effects
… of different mechanical structures of aluminum beams, lug samples and railroad switch bolts. The experimental study of the aluminum lug samples and beams is done to propose and examine methods and models for in situ interrogation and detection of damage (in the form of a fatigue crack) in these …
