Effects of adhesive thickness on the mode I cohesive zone model parameters of a high toughness structural adhesive

摘要

The automotive industry is currently increasing its use of structural adhesives to reduce vehicle weight and improve crash resistance. The development of design criteria for structural adhesives are essential to increase designers’ confidence and consequently its utilization. A recent approach consists in the use of Cohesive Zone Model (CZM) through Finite Element Method (FEM) programs. A CZM requires a traction-separation
