RESUMO

The tact may be defined as the capacity of a body to locate the contact on its surface, to recognize shape of the contacting surface as well as the superficial rugosity. Usually analytical models are not able to describe the phenomenon properly. This work, proposes an approach for the contact form location between two bodies using the resultant signals analysis of the vibrations caused for the contact. In this way it is determined the target surface geometry. The qualitative description of the impact is obtained through the analysis of mathematical series that generate orthogonal basis for this sort of event. Thus, the contact is not considered through a traditional physical modeling, but by the description of the waves generated for the superficial stress and strain, incorporating the interaction of multiple entailed points and procedures of counting statistics. With a methodology for study of theoretical impact, the quantitative construction of the specter of displacement of a subject plate to the application of distributed strains is effected.
