Abstract

With the development of urbanization, accurately determining the material properties of underwater facilities or structures, such as bridges, under continuous bending load is essential to ensure safe and stable operations. However, the underwater environment is difficult to access, making on-site mechanical property tests challenging due to fluid pressure. Traditional mechanical property measurement methods are often not applicable in underwater environments. This study presents a non-destructive method for flexural modulus measurement underwater using immersion ultrasound transmission and a four-point bending test. The proposed method can be developed as an integrated wireless system for real-time underwater mechanical property measurement.
