Research on the Elastic Loss Characteristics of Acoustic Echoes from Underwater Corner Reflector [PDF]

open access: yesSensors
The underwater corner reflector is a “concave” elastic structure, and its acoustic echo exhibits large elastic loss, which affects its practical use. To study the acoustic echo elastic loss characteristics of underwater corner reflectors, based on the ...

A Unified Nonlinear Elastic Model for Rock Material

open access: yesApplied Sciences, 2022
Under conditions of low or medium stress, rocks that are in the compression state exhibit perceivable nonlinear elastic characteristics. After a comprehensive review of the existing nonlinear elastic models of rocks and joints, we proposed a new unified ...

Theoretical modelling of frequency dependent elastic loss in composite piezoelectric transducers [PDF]

open access: yes, 2007
The large number of degrees of freedom in the design of piezoelectric transducers requires a theoretical model that is computationally efficient so that a large number of iterations can be performed in the design optimisation.
