CONSIDERATIONS REGARDING CORROSION EFFECTS
ON BEAMS DYNAMIC BEHAVIOR
Negative effects caused by corrosion are significant, both economically
and in terms of public safety, so incipient detection of corroded areas is
necessary to take in real-time measures to prevent the occurrence of
dangerous situations. This paper presents types of corrosion and various actual
methods used to detect corroded areas together with a new approach in
damage detection based on vibration measurements. While the proposed
method base on frequency changes, to understand the dynamic behaviour of
beams subjected to corrosion is a first step. It permits establishing appropriate
mathematical models and development of damage detection methods implying
the monitoring and analyzes of beams natural frequencies.
