Mechanical performance of composite bonded joints in the presence of localised process-induced zero-thickness defects [PDF]

open access: yes, 2018
Processing parameters and environmental conditions can introduce variation into the performance of adhesively bonded joints. The effect of such variation on the mechanical performance of the joints is not well understood.
