Autonomous machine learning algorithm for stress monitoring in concrete using elastoacoustical effect
The measurement of stress in concrete structures is a complex issue. This paper presents a
new measurement system called a self-acoustic system (SAS), which uses frequency
measurements of acoustic waves to determine the condition of concrete structures. The SAS
uses a positive feedback loop between ultrasonic heads, which causes excitation to a stable
limit cycle. The frequency of this cycle is related to the propagation time of an acoustic wave,
which directly depends on stresses in the test object. The coupling mechanism between …
