Guided Waves for Damage Monitoring In Plates with Corrosion Defects
Non-destructive testing techniques are the preferred techniques in this new era of development and progress. Health monitoring of different mechanical and civil structures during its service is very important for the safety of human beings. Health monitoring of these structures using ultrasonic technique is an emerging field. It uses high frequency sound waves into the material to detect and locate defects, discontinuities in the material. This paper presents the use of pulse echo technique of ultrasonic to detect corrosion defect in mild steel plates and the behaviour of different frequencies at various levels of corrosion. For different damage types, most ideal modes and frequencies were selected for testing.
