Design improvement of a composite-to-steel butt-joint based on finite element analysis

A composite-to-steel butt-joint applied to joining large composite sandwich panels to steel ships is studied and its design is improved based on numerical simulations combined with test results. A cohesive zone model is adopted to simulate interfacial debonding of the joint. Cohesive property parameters of the interfaces are obtained by multiple calculations and comparisons with experimental results. Three schemes for improving the design of the joint are proposed. The numerical simulation results of the improvement schemes based on the cohesive parameters obtained before indicate that these three schemes can effectively relieve the shear stress concentration and improve the stress field on the critical region, thus delaying the interfacial debonding and the core strength failure, thus increasing the bearing capacity of the joint.
