EXPERIMENTAL ANALYSIS OF AN CRACKED ADHESIVE JOINT
Keywords:
adhesive joints, pmma-polyurethane, crack propagation, mode-I failure, load vs displacementAbstract
Adhesive bonding is an alternative toconventional joining systems (e.g., riveting or welding) for a numerous class of
components belonging to electronic, automotive, and aerospace industries. However, adhesive joints contain flaws;
therefore, the development of such technology requires reliable knowledge of the corresponding fracture properties. This
study deals with ideology to obtain a specific Load vs displacement relationship based on the problem for
PMMA/polyurethane adhesive joint along with stresses and crack length relation establishment, on Mode-I conditions
directly through experiments. This information is valuable for predicting the durability of a structure containing
adhesively bonded joints.
