Hybrid analysis of two-and three-dimensional solids composed of different materials

摘要

Modern methods in experimental mechanics require considerable expenditure of theoretical considerations with concern to the experimental methods themselves as well as with concern to reliable evaluation and interpretation of the measured data. Because of the high resolving power and the exact data recording it is necessary to consider comprehensively all, even very small effects, which may have influence on the results of measurement. Otherwise the impression of an apparent accuracy may arise. On the other hand it is necessary to transform the originally measured data into the finally wanted information, which generally do not coincide with the measure quantities. Therefore the conventional interpretation of observed phenomena, i.e. measured data, must be substituted by advanced mathematical algorithms, enabling correct evaluation of data into wanted information in order to better approaching the reality. As measurements yield discrete information only the mathematical algorithms must be translated into discrete numerical procedures.
