Summary The inverse procedures in engineering dynamics involved in system identification, damage detection and model calibration are highly nonlinear. New advances in bionics e.g. Genetic Algorithms, Artificial Neural Networks encourage their application in nonlinear field where versatile and robust procedures are required. The developed methods, algorithms and procedures will enhance inverse procedures in system identification, model validation and damage detection and contribute there accuracy, stability and reliability. It is assumed that application of the advanced bionics based algorithms in inverse tasks in dynamic analysis of structures and machines can lead to the reliable tools for a) system identification b) model validation c) and damage detection. It is expected that at the end of the project bionics based algorithms will be developed and implemented for model validation and calibration as well as algorithms for damage detection. The development of the algorithms will be performed using numerical simulation of mechanical models. The developed algorithms and procedures will be tested on a number of the physical mechanical models using measured data.

Key words |numerical and experimental modal analysis|procedures of model calibration and validation,damage detection,inverse analysis
