Q1. What contributions have the authors mentioned in the paper "Fracture mechanics and damage mechanics based fatigue lifetime prediction of adhesively bonded joints subjected to variable amplitude fatigue" ?
The first part of the paper describes an investigation into the behaviour of adhesively bonded single lap joints ( SLJs ) subjected to various types of variable amplitude fatigue ( VAF ) loading. In the second part of the paper, fracture mechanics ( FM ) and damage mechanics ( DM ) approaches are used to predict the fatigue lifetime for these joints.
