Analyzing Adhesively Bonded Joints Subjected to Torsional Loading: Experimental and Numerical Investigation.

Abstract

In this scholarly exposition, a comprehensive investigation is conducted on adhesively bonded joints, employing a combination of experimental and numerical methodologies. These joints involve intricate male and female components made from both metallic and non-metallic materials. The study delves into a meticulous analysis, manipulating the thickness of the adhesively bonded joints. By altering the diameter of the male component, three distinct thickness variations in the adhesive joints are meticulously considered. Rigorous torsional tests are conducted within a laboratory setting, generating a plethora of data. The study intricately explores the strength of these bonded connections through sophisticated numerical analyses, focusing on the nuanced impact of adhesive thickness and overlap length. To validate the theoretical model, the numerical results are meticulously juxtaposed against the experimental findings, revealing a remarkable congruence between the two. Notably, the research findings elucidate that heightened adhesive joint thicknesses diminish the overall joint strength, while thinner adhesive joints exhibit limited torque transmission capabilities. Moreover, the study discerns a profound influence of the adhesive bonding's overlap length on the maximum shear stress, notably noting a significant peak at a 60 mm overlap length. These findings underscore the critical importance of meticulously investigating adhesive joint thickness in the realm of design and engineering.
