Erman Evgin, P.Eng., Ph.D.
Present research interests of Dr. Evgin are listed below:Dr. Evgin started his career as a field engineer on the construction of Keban Dam, Turkey in 1967. Subsequently, he gained additional experience in dam engineering by working on various stages of the Churchill Fall Hydro-Electric Power Project, Labrador, Canada between 1970-72. In the following years, his interest shifted toward research. During his M.Sc. studies at McGill University, he carried out experimental and theoretical studies on the behaviour of single and groups of piles. In his Ph.D. work between 1975 and 1980 at the University of Alberta, he developed a nonlinear finite element program, modified Lade's elastoplastic soil model, implemented the model into the finite element program, and successfully simulated the behaviour of a fully instrumented model-scale retaining wall.~ BIOGRAPHY ~ After his doctoral studies, Dr. Evgin worked as a consulting engineer for Dome Petroleum Ltd. He implemented a nonlinear soil model into a well-known general-purpose finite element program, ADINA, and carried out various three dimensional finite element analyses of artificial islands and caisson-retained islands subjected to ice loads in the Beaufort Sea. Before joining the University of Ottawa, he worked at the National Research Council of Canada from 1984 to 1986. During that period, he developed a new method to analyze data from a dual gamma ray machine. This nondestructive testing method was used to determine the water content and density changes in soil samples during a drying process. Dr. Evgin has been a professor at the University of Ottawa since 1986. Between 1986 and 1992, he conducted research with his graduate students in the mathematical modelling of cyclic behaviour of soils and ice. These models were all implemented into finite element programs and were used to solve real engineering problems such as pile foundations, pipelines and offshore structures.
Between 1992 and 1996, Dr. Evgin and his former student Dr. Fakharian developed a unique apparatus to study the behaviour of soil-structure interfaces subjected to cyclic loading. This apparatus was the first interface apparatus with 3-D loading capabilities reported in the literature. The interface apparatus has been used in the investigation of (a) the reasons for the degradation of shaft resistance of piles under two-way cyclic loading conditions, (b) the effects of various stress paths on interface behaviour, and (c) the cyclic rotational simple shear response of sand-steel interfaces.
Dr. Evgin spent his sabbatical leave in Grenoble, France working with Professor M. Boulon on oil-contaminated interfaces. On his return to Canada, he served as an associate editor to the Canadian Geotechnical Journal for several years.Dr. Evgin has been continuing to work on both practical and theoretical aspects of soil-structure interaction problems. Recent graduate students completed their studies by using nonlinear finite element analyses in the simulation of the measured behaviour of pile foundations and pipelines.
Former graduate students of Dr. Evgin found employment as research officers at the National Research Council of Canada, heads of well known geotechnical firms, geotechnical design engineers in various Canadian as well as international consulting firms and as a university professor.
