Input data |
・ , the successive time points, at which the FSR measures the normal stress at the inner surface of the BS, ・ , the values of the stress measured by the FSR at the above time points ・ , the parameter determined from the calibrating identification as is described in Remark A.2 ・ , the thickness of the BS ・ Optional: an analytical or tabular dependence of the speed of the bulk acoustic waves in the BS on the volumetric mass density of the BS (i.e., dependence in Remark A.1) |
Parameters that can be identified |
At any three successive time points measured by the FSR (see the upper half of this table), one can identify the following parameters: ・ , the speed of the bulk acoustic waves in the BS ・ , the stress-relaxation time of the BS ・ , the source term in the acoustic equation (see the text on (A.31) and (A.32)) ・ , the volumetric mass density of the BS (if the above option is available) ・ , the bulk modulus of the BS (if the above option is available) |
