Abstract:
Bonded repairs of metallic structures, particularly using composite materials, have gained wide research attention in the past decade. However, the debonding strength of bonded joints exhibits a relatively high uncertainty compared to other strength-based limit states in structural applications. This uncertainty is compounded by various factors including the difference between the tensile and shear responses of typical polymeric adhesives, the effect of surface preparation on failure modes and capacities, and the interaction between interface strength and interface toughness. This presentation summarizes the ongoing experimental and analytical research efforts at the University of Houston to help quantify the uncertainty in the strength of bonded joints in metallic structures with an emphasis on the bond between steel and carbon fiber reinforced polymers.

Mina Dawood is an Associate Professor in the Department of Civil and Environmental Engineering at the University of Houston where he has been a full-time faculty member since 2009. His research interests lie broadly in the field of implementation of new materials in civil infrastructure applications for both new construction and repair and rehabilitation of existing structures. Dr. Dawood is an Associate Editor of the ASCE Journal of Composites for Construction and a member of the Council of the International Institute of FRP in Construction (IIFC). He has co-authored nearly 50 archival journal publications and a comparable number of conference papers. He has been a PI or Co-PI on research projects funded by the National Science Foundation, US Department of Education, National Cooperative Highway Research Program, Qatar National Research Fund, Texas Department of Transportation, and private industry.
