Experimental Analysis on Conditions of Joint for Cantilever Beam
초록
Joints are used extensively in various industries. For instance, structural adhesives are used in place of the traditional mechanical fasteners, such as screws and bolts, because they are much lighter and spread the stresses more uniformly across the joints. For efficient designs of joints, knowledge of static and dynamic characteristics of joints is essential. Most analysis of joints are carried out using analytical equations or finite element method. In this paper, the characteristics of four conditions of lap-joint beam are investigated experimentally. The mode shapes and nodal points of beam show that there are different deformations in each condition. These deformations may cause high stresses and may initiate local cracking and delamination failures.
