Professor Delale has over 70 refereed publications dealing with a wide array of damage and failure problems in composite materials. His early contributions were in extending fracture analysis to anisotropic layered media and considering the Reissner effect in the solution of crack problems in plates and shells. In collaboration with Professor Erdogan of Lehigh University he has developed an interface model for bonded materials. His most recent research interests are in the area of high temperature composites. With Professor Liaw of CCNY he has developed a novel technique to test composites at high temperatures in an SEM and observe and record the damage until failure.
