The Cohesive Zone Model (CZM) is a powerful tool for the simulation of fracture in bonded assemblies. In this chapter the CZM is employed in order to study the enhancement of bond toughness in adhesive joints with laser irradiates substrates. The chapter rst discusses the implementation of an interface element, incorporating the Park-Paulino-Roesler (PPR) potential-based cohesive model [Park et al., 2009], in the framework of a nite element commercial code (ABAQUS Standard).

Abstract
The Cohesive Zone Model (CZM) is a powerful tool for the simulation of fracture in bonded assemblies. In this chapter the CZM is employed in order to study the enhancement of bond toughness in adhesive joints with laser irradiates substrates. The chapter rst discusses the implementation of an interface element, incorporating the Park-Paulino-Roesler (PPR) potential-based cohesive model [Park et al., 2009], in the framework of a nite element commercial code (ABAQUS Standard). Afterward, the PPR is applied in order to simulate de-bonding in T-peel joints, with laser treated substrates, failing with large plastic deformations.File in questo prodotto:
