Abstract: | A numerical–analytic method for the identification of the axisymmetric mechanical shock load on a disk-shaped metal–piezoceramic
bimorph transducer is proposed. A problem is formulated based on the theory of thin two-layer plates. The solution is found
using the Laplace transform. By recovering the original function analytically, the problem is reduced to a system of Volterra
equations, solved numerically using Tikhonov’s regularization algorithm. The finite-element solution of the direct problem
is used as input data (potential difference between the electrodes of the piezoceramic layer). The results are analyzed |
