Abstract

This study deals with damage tolerance of sandwich X-joints with embedded debond damages between face and core. The study is conducted both through modeling and full-scale tests. Mixed mode cohesive laws from the opening of sandwich interfaces are determined experimentally from a DCB specimen loaded by moments, and the results are utilized in a cohesive zone model of a tested sandwich structure. Results of the crack propagation from experiments and simulation show fair agreement. Design aspects regarding the influence of debond size and core inserts on the residual strength are discussed.
