Richard B. Hetnarski

Richard B. Hetnarski (May 31, 1928 – June 8, 2024) was a Polish-born American academic and translator who was a professor in the department of mechanical engineering at Rochester Institute of Technology. He was an ASME Fellow since 1983 and a New York State Licensed Professional Engineer since 1976. He is best known for his contributions to the fields of Thermal Stresses and Thermoelasticity.

Early life and work Richard B. Hetnarski was born in Stopnica, Poland. He received a Master of Science degree in mechanical engineering at Gdańsk University of Technology in Poland in 1952; In his career he concentrated his research on Solid Body Mechanics. (1970–1971), then as Professor He became a professor emeritus in 1998.

In 1979, he held a summer faculty fellowship at the NASA Lewis Research Center in Cleveland, Ohio. Then, in September 1979, he taught a UNESCO sponsored course at the International Centre for Mechanical Sciences (CISM) as an aeronautical engineer, and worked at NASA in Cleveland until the end of January 1980. Later, he spent five months as Visiting Professor at the University of Paderborn in Germany. Hetnarski was known for his deeply pro-democracy convictions. In 1989, when the Communist government in Poland was collapsing, he gave a number of presentations on the subject at three TV network affiliates of NBC, ABC, and CBS. When Lech Wałęsa, Nobel Peace Prize winner and former president of Poland, visited Rochester Institute of Technology in February 1998, he and Wałęsa discussed the political situation in Poland, later described in the Rochester Democrat and Chronicle, February 22, 1998 edition.

Hetnarski died in Naples, Florida, on June 8, 2024, at the age of 96.

Achievements Professor Richard B. Hetnarski, at the opening ceremony of the 10th International Congress on Thermal Stresses in Nanjing, China, on 1 Jun 2013. He is presenting the book "Theory of Elasticity and Thermal Stresses" which just got published. Hetnarski was the founder (with Naotake Noda) and president until 2020 of the International Congresses on Thermal Stresses (ICTS). These Congresses are held every two years consecutively on three continents, that is, in Asia, America, Europe. The first meeting was held June 5–7, 1995 in Hamamatsu, Japan at Shizuoka University These were titled First and Second International Symposium on Thermal Stresses and Related Topics, respectively. The name International Symposium on Thermal Stresses and Related Topics was changed to International Congress on Thermal Stresses with the meeting in Kraków, Poland at Cracow University of Technology on June 13–17, 1999. In 2002 the International Congresses on Thermal Stresses (ICTS) became an Affiliated Organization of International Union of Theoretical and Applied Mechanics (IUTAM).

Hetnarski was active in teaching, research, publishing, translating, and editing. He is the author of many papers was published in the ASME Journal of Mechanisms and Robotics in 2020 when he was 92 years old.

Editor and translator work

In 1978, Hetnarski founded the Journal of Thermal Stresses, (1978–2018), and was later its Honorary Editor. He served (1988–1991) as an Associate Editor of Applied Mechanics Reviews.

He was Editor of the 11-volume Encyclopedia of Thermal Stresses, 6643 pages, Springer, 2014. Also, he was Editor of the five-volume Thermal Stresses handbook which was published by Elsevier in Amsterdam and by Lastran Corp. in Rochester, New York, in the years 1986–1999.

Hetnarski translated or co-translated three books into Polish from Russian, from German, and from English, and one from Russian into English. He edited five books on Mechanics.
