Outlook & motivations
• Cohesive Zone Model for interface decohesion
• Extension to thermomechanical problems
1. Generalize thermoelastic contact analysis to fracture
(Zavarise et al. 1992; Wriggers and Zavarise, 1993)
2. Propose a simpler and physically consistent
formulation where the interface conductance depends on
crack opening, as an improvement and generalization of
other formulations
(Hattiangadi & Siegmund 2004; Yvonnet et al. 2010;
