Aspects Regarding the Hybrid Models in Engineering

Abstract

Physical phenomena in engineering are studied using several types of research instruments. In the class of the theoretical instruments may be considered the analytic and numeric models and the category of the practical approaches includes the experimental studies. However, complex phenomena require information resulted from several types of studies. The integration of the information may be done using original software applications which offer speed, accuracy and flexibility in the context of that certain project. If the research plan considers right from the beginning the integration of the results of different types of studies in a unique investigation methodology, the model of the phenomenon may be considered hybrid. The paper presents several research projects in engineering, the project dedicated to the strains and stresses in the cylinder block is the most complex one and it required several studies of different types, together with original software employed to integrate the data. It may be considered a relevant example of hybrid model. To conclude, the analysis of the phenomenon to be studied must lead to a certain high overview which offers the grounds of a holistic approach in the design of the research plan. Thus, there must be identified all the sources of experimental data, using various experimental techniques, even the redundant information being useful for cross-checking purposes.
