Abstract
En 中文
The presence of particles at a bonding interface is responsible for unbonded areas. In this paper we relate the unbonded area to the characteristics of the defects (height and diameter). This analytic expression is derived from elastic energy calculations based on classical point force and flat punch models. The results from the analytic formula are compared to finite element modeling calculations using J-integrals, with different experimental input parameters. Bonding energies of a series of samples with controlled defects are then obtained consistently using both methods.
