Education Ph.D. in solid mechanics, Brown University, RI, 1966. M.S. in structural engineering, Lehigh University, PA, 1963 B.S. in civil engineering, National Cheng-Kung University, Taiwan, 1959 Research Interests Constitutive modeling of engineering materials, soil and concrete plasticity, structural connections, and structural stability Citation For his pioneering research and leadership in the fields of structural engineering and mechanics of materials. As author, teacher, editor, and leader, his work and enthusiasm have brought the rigorous theory of plasticity to civil engineering practice, particularly of the second-order inelastic analysis for structural design and constitutive modeling of engineering materials.Blurb
