| Abstract |
We present a method for solving nonlinear inverse problems, which also include identification problems for elastic systems. The problems whose initial data contain an error are usually solved by regularization methods [1-5]. In the present paper, we give preference to Tikhonov's regularization method, which has been widely used in the recent years in practice to increase the stability of computational algorithms for solving problems in various areas of mechanics [6-9].
The identification problem for elastic systems is posed in the variational setting. We obtain an unconditional optimization problem, which is solved by the Newton method. We present a numerical example of identification of a single-span beam. An analysis of the obtained numerical results shows that it is necessary to solve the identification problems for elastic systems by regularization methods. |
