Abstract The configuration of adhesive bonding, especially adhesive–adherent interface, is very important in adhesive bonding. Adherend thickness, overlap length and adherend width have a great effect on failure load. It is important to know the effect of these parameters in the estimation of failure load. In this study, two models based on data mining techniques were generated for the estimation of the effect of adherend thickness, width and overlap length on failure load in adhesively bonding joints. One of the models is based on the M5P model tree and the other is based on the M5 rule algorithm. Experimental data were used to evaluate the performance of the models. The correlation coefficient parameter was used to compare the models’ performance. The evaluated correlation coefficient is 93% for the M5P model tree and 96% for the M5 rule.

1 Introduction Adhesively bonding joints have a wide range of uses. They have an especially important place in the aviation and automotive industries Adhesive bonding has attracted considerable attention in various industries as a replacement for traditional joining methods such as riveting, bolting and welding [1]. The need to design lightweight structures and the increased use of lightweight materials in industrial fields have led to the wide use of adhesive bonding [2]. Adhesively bonded joints provide many advantages over conventional bonding, such as they provide a more uniform stress distribution along the bonded area, have high corrosion and fatigue resistance and reduce the weight and the cost [3]. They also need fewer components, different materials with dissimilar thicknesses can be assembled with adhesives and they are energetically efficient and easy to automate [4]. Adhesive bonding is a particularly attractive bonding method that allows different materials to be joined without damaging the main structures and is used to produce Technical Editor: Paulo de Tarso Rocha de Mendonça, Ph.D. * Yaşar Ayaz [email protected] 1

structures of complex shapes that could not be manufactured in one piece [5]. To date, many studies related to adhesively bonded joints have been performed. Adhesives were used in different materials, such as steel, aluminum, and composites for bonding. The configuration and dimensions in adhesively bonding joints, especially in the adhesive–adherent interface, are also very important. Liu and Wang studied the stress behavior in layers of carbon fiber-reinforced polymer (CFRP) adhesively bonded double strap joints subjected to the tensile stress using the finite element method and
