Abstract

In this paper, we present a multivariate correlation between the main geometrical parameters

affecting the mechanical strength of an adhesive joint, unlike traditional studies only consider the

influence of each factor independently. Was selected the adhesive thickness, the length of overlap

of the joint and the surface roughness of the contact elements as representative parameters, which influence the mechanical strength of an adhesive joint with a cylindrical geometry. The joint of these two elements made of an anaerobic adhesive was subjected to controlled torsion test to determine the maximum ultimate load. We used the experimental design methodology to assess a region 2k factorial, replicated three times. The analysis of variance in conjunction with Pareto`s has allowed identify the statistical significance of each of the geometric parameters. Finally, a regression model and response surfacewere used to explain the mechanical behavior of the joint considering the most significant statistical treatment.
