RESEARCH INTERESTS
Combines analytical, computational and experimental aspects and aims at gaining basic
understanding of material response and the development of predictive models.
Recent interests have focused on environmental effects and the modeling of damage in
composites. During the past twenty-five years engaged in research on the mechanical
response of polymers and composite materials.
Current research contracts: "The Hydro and Thermal Response of Thermoplastic
Composites" (supported by ONR) and "The Mechanical Response of Cross-Ply and
Angle-Ply Ceramic Composites" (supported by AFOSR).
Recently concluded contracts: "Investigations of Environmental Effects and
Environmental Damage in Composites" (supported by ONR), "Time-Dependent and
Damage Behavior of Polymeric Composites and Resins" (supported by ONR) and
"Residual-Stress Induced Damage in Composites" (supported by AFOSR).
Recipient of contracts from NSF, ARPA, U.S. Army, AFML, AFOSR and ONR.
