Mechanics of Direct Bonding: Splitting Forces

This study attempts to fill this knowledge gap in the mechanics of bonded structures. Herein, we propose a model that allows the calculation of the splitting forces in the basic part of the bonded bilayer where the internal stresses along interface are uniformly distributed. The calculations reveal three possible distributions of the splitting forces in the bonded structure, i.e., the splitting forces could be either located at the center or the periphery—which also includes the edges of the structure, or could be completely absent regardless of the total magnitude of the residual stresses. The results obtained could be used in bonding technology as an immediate guide to increasing the bonding strength between dissimilar materials.Graphical abstract
