Application of Boundary Inverse Methods in Civil Engineering

Popis výsledku v původním jazyce

In specific fields of research such as treatment of historical structures, medical imaging, material science, geophysics and others, it is of particular interest to perform only a non-intrusive boundary measurement. The idea is to obtain a comprehensive information about the material properties inside the domain under consideration while maintaining the test sample intact. This statement is focused on such problems i.e. synthesizing a physical model of interest with a boundary inverse techniques. The forward model is represented by three diffusion based models with Finite Element (FE) discretisation and the parameters are subsequently recovered using a modified Calderón problem principles which is numerically solved by a regularised Gauss-Newton method. We provide a basic framework, implementation details and modification of general constrains originally derived for a standard setup of Calderón problem. The proposed model setup was numerically verified for various domains, load conditions and material field distributions. Both steady-state and time dependent cases are studied.
