Civil and Environmental Engineering

Upon receiving his Ph.D., Professor Herrmann worked in the Aerospace industry as a Senior Research Engineer form 1962-1965; he joined the faculty at UC Davis in 1965. He has served as a technical consultant for numerous Civil and Aerospace Engineering firms. In 1992 he received the $25,000 UC Davis Prize for Teaching and Scholarly Achievement.

Professor Herrmann's research interests are in the general areas of solid and structural mechanics, and finite element analysis with applications in Civil, Aerospace and Geotechnical Engineering and to homogenized modeling of composite materials and systems. They include the development and application of advanced Finite Element procedures for steady-state dynamic problems in Geotechnical Engineering where the soils are characterized by elastic-plastic behavior; applications include the determination of the soil disturbance produced by sampling devices and the determination of the force required for the high speed trenching of the sea floor. Current research in the homogenized modeling of composite systems includes the development and numerical implementation of a plasticity model for the bond between reinforcement and concrete.

Dr. Herrmann has been the recipient of the UC Davis Academic Senate Distinguished Teaching Award; the UC Davis Prize for Teaching and Scholarly Achievement; and the American Society for Testing and Materials, Hogentogler Award.
