Advanced Numerical Techniques to Design T-bonded Joints | Chapter 5 | Technological Innovation in Engineering Research Vol. 4

Adhesive bonds have become more popular in industrial settings as a result of their numerous benefits over other, more conventional bonding techniques (fastened, welded and riveted joints). Over time, there have become more methods for predicting the strength of adhesive junctions. Although it is rarely researched in relation to bonded joints, the eXtended Finite Element Method (XFEM) is a modern variation of the (Finite Element Method) FEM to simulate damage development in structures. Three T-joints made of an aluminium alloy that have been adhered together are the subject of an experimental and XFEM analysis in this study. With values ranging from 1 to 4 mm, the thickness of the curved adherends (tP2) is examined parametrically. The ability of XFEM prediction was evaluated using various damage start and propagation criteria. It was shown that if the modelling conditions are properly specified, accurate numerical results may be obtained.
