文摘

A cracked aluminum pipe repaired by glass/epoxy composite patch is studied under fatigue tension loading. Experimental tests are validated by extended finite element method. The model simultaneously simulates the fatigue crack growth in the pipe besides debonding failure in the adhesive layer. XFEM method is utilized to model crack growth in the cracked pipe. Cohesive elements are implemented to consider debonding in adhesive layer.
