In this paper, the fused silica glass direct bonding is studied to understand its mechanical behaviour. A phenomenological law, using Cohesive Zone Model (CZM), is described to model direct bonding. This model is based on several experiments which allow determining the fracture energy G (wedge test) and the fracture initiation load F (cleavage test).

Mots clés: direct bonding; cohesive zone model; wedge test; fracture initiation
