The article discusses an algorithm developed for the detection of material properties and thickness of a layered solid body. The algorithm combines system equations and data from measurements taken in time intervals. The heat conduction equation, uncoupled thermoelasticity equations, and equations of motion (elastodynamic equations) are used to formulate an optimal estimation problem that seeks to minimize the error difference between the given data and the response from the system. Since all measurement instruments are error prone, the influence of an artificially generated measurement error on the accuracy of the solution is investigated. The method leads to an iterative algorithm that at every iteration requires the solution of a two-point boundary value problem. The numerical results indicate that a close estimate of the unknown material properties and thickness of the three-layered body can be obtained based on the displacement and temperature measurements on a temporal interval. The method was tested on the simulated experimental data. |
