| Abstract Scope |
Bonded interfaces play a critical role in lightweight aerospace structures and are increasingly important in ceramic and glass joining applications where interfacial failure governs structural integrity. This work presents a computational fracture framework based on zero-thickness cohesive zone modeling (CZM) to predict interfacial crack initiation and propagation under Mode I and Mode II loading. The approach is validated against benchmark fracture configurations using experimentally reported load- displacement responses from the literature. The validated zero-thickness formulation establishes a computational foundation for predictive assessment of bonded interfaces and provides a basis for future studies incorporating finite-thickness adhesive layers in complex joint geometries. Ongoing work integrates advanced nondestructive evaluation, including neutron imaging, to correlate simulated damage evolution with experimentally observed fracture behavior. The approach establishes a computationally efficient baseline for predicting interfacial fracture and serves as a foundation for future investigations of finite-thickness adhesive layers, complex bonded geometries, ceramic and glass joining systems. |
