Acoustic digital twin for passive structural health monitoring
Autor: Simone Sternini, Alexis Bottero, W. A. Kuperman
Publikováno v: JASA express letters. 2(2)
This study presents simulation results on passive structural health monitoring of a vibrating elastic structure for defect localization. The object considered in this study consists of a shell equipped with vibration sensors surrounding a vibrating s

Inferring the characteristics of marine sediments from the acoustic response of a known, partially buried object
Autor: Alexis Bottero, Simone Sternini, Jit Sarkar, W. A. Kuperman
Publikováno v: The Journal of the Acoustical Society of America. 152(1)
We investigate the feasibility of using a known elastic target located near the seabed for the purpose of inferring characteristics of marine sediment. In the problem considered the object position and its burial depth are not known with precision. F

Journal of the Acoustical Society of America, 2020, 148 (2), pp.734-747. ⟨10.1121/10.0001705⟩
This paper presents a method to calculate the bistatic response of an elastic object immersed in a fluid using its structural Green's function (in vacuo structural admittance matrix), calculated by placing the object in a spatially random noise field

Infering the characteristics of marine sediments from the acoustic response of a known object
Autor: Simone Sternini, William A. Kuperman, Alexis Bottero
Publikováno v: The Journal of the Acoustical Society of America. 150:A157-A157
The acoustic response of an object depends on the surrounding environment. We show here how to take advantage of a known elastic target located near the seabed to infer characteristics of marine sediment. The approach consists of several steps. First

Numerical simulations of T-wave generation and conversion at shores: Influence of slope angles and of the SOFAR channel
Autor: Alexis Bottero, Dimitri Komatitsch, Paul Cristini

The term T waves is generally associated to acoustic signals generated by earthquakes which end up traveling horizontally in the ocean at the speed of sound in the water. After traveling over long ranges they reach the shore, where they can be reflec
