Timoshenko: Father of Engineering Mechanics

The legend of Timoshenko has few parallels in the annals of publishing technical books. For reading and understanding engineering mechanics the books of Timoshenko permeate a Shakespearean aura of authenticity and authority somewhat like Chandrasekhar's books on astrophysics. Timoshenko's books have been printed, sold, translated and reprinted in millions across the world ever since 1908 with the publication of his first book on strength of materials in Russian. His books have been translated into many major and minor languages including Arabic, Bengali, Fanti, French, Ga, Malay, Swahili, Urdu.... The list goes on and on as the Timoshenko legend grows bigger and bigger all the time....

Ludwig Prandtl, A great mechanician!

Ludwig Prandtl's contributions to fluid mechanics include his development of lifting line theory (to describe the lift and drag of wings of finite span), his work in turbulence, and his experimental and theoretical studies of gasdynamics. Prandtl was trained as a solid mechanist and continued to contribute to solid mechanics throughout most of his career. However, his discovery of the boundary layer is regarded as one of the most important breakthroughs in fluid mechanics of all time and has earned Prandtl the title of Father of Modern Fluid Mechanics.

In Memoriam: Erastus H. Lee

Erastus H. LeeErastus H. Lee, professor emeritus and a prominent researcher, with fundamental contributions to plasticity, viscoelasticity and wave propagation, died at the age of 90 on May 17, 2006, in Lee, New Hampshire.

Ras Lee was born on February 2, 1916, in Southport, England. He graduated from Cambridge University in 1937 with a bachelor degree in mechanical sciences and mathematics. After a further year of postgraduate study at Cambridge with Professor C. E. Inglis, Ras was awarded a fellowship from the Commonwealth Fund of New York to study with Professor Stephen Timoshenko at Stanford University. He completed his Ph.D. degree in 1940 and immediately thereafter became involved in the British war efforts during World War II. He worked first as a progress officer in the British Purchasing Commission in New York and later in the British Air Commission in Washington. Officer Lee was concerned with planning aircraft deliveries from U.S. companies and keeping records of modifications required to meet British needs.

David Turnbull died on 28 April 2007

David Turnbull died peacefully at home last Saturday, April 28th, at age 92.

He was for many years Gordon McKay Professor of Applied Physics at Harvard University. His seminal work included theoretical and experimental studies of nucleation of crystals, the glass transition and the amorphous state, crystal growth, and atomic diffusion.

In 1992 the Materials Research Society (MRS) established the David Turnbull Lectureship to recognize each year the career of a scientist who has made outstanding contributions to understanding materials phenomena and properties through research, writing, and lecturing. His autobiography and a biography are available on the MRS website.

He retired in 1985 but was active and visited his office on the second floor of Pierce Hall right up until the last six months or so.

In Memory of Professor Liviu Librescu

I had known Liviu since his early days in the Engineering Science and Mechanics Department at Virginia Tech when I was just beginning my own academic career. I had received my PhD from this department in 1981 in an area (composite materials) that at the time was at the cutting edge of high technology. In 1985 I had come back to VA Tech from the industry to continue working in this exciting area in which the ESM Department excelled world-wide. Liviu had arrived shortly thereafter with an already established reputation as a top-notch scientist. I was drawn to him because his background and life experiences during WWII and thereafter in his native Romania were similar to my parents' experiences in Poland.

Dr. Kevin Granata

Kevin P. Granata, 45, of Blacksburg, beloved husband and father, loving son and brother, passed away Monday, April 16, 2007. Kevin was born and raised in Toledo, Ohio. He began his bachelor's studies at John Carroll University in Cleveland, Ohio and then transferred to Ohio State University where he received degrees in electrical engineering and physics. He later earned a Master's degree in physics from Purdue University and was employed by the Applied Physics Lab in Maryland where he did classified research. He returned to Ohio State University and completed his Ph. D. in Biomedical Engineering, continuing his research until he transferred to the Department of Orthopedics at the University of Virginia, where he was the director the Gait Lab In 2002, Kevin came to Virginia Tech in Blacksburg, Va. to continue his teaching and research interests. He had numerous publications and research grants and lectured both nationally and internationally. Kevin's greatest passion and pride was his family, especially his wife and children. He was also an athlete. He rowed crew at Purdue, participated in biathlons and triathlons and was an avid runner and cyclist. He loved coaching his sons' Lacrosse teams, reading and doing construction around his home and was a member of St. Mary's Roman Catholic Church. Kevin believed in being a well-rounded person and he successfully used his talents to the utmost, academically, physically and spiritually. He will be greatly missed. He is survived by wife, Linda (nee Ankenman); sons, Alex and Eric; and daughter, Ellen; parents, Mildred and Joseph Granata (Toledo); brother, Paul; sisters, Eileen and Anne; and numerous nieces and nephews, aunts and uncles. A public memorial service will be held at the Blacksburg Presbyterian Church at 2 p.m. Friday, April 20, 2007. A private funeral will be held. In lieu of flowers, memorials can be made to the Kevin P. Granata Memorial Trust, 1872 Pratt Drive, Blacksburg, Va, 24068. Arrangements by McCoy Funeral Home, 150 Country Club Drive, Blacksburg, Va.

Virginia Tech Tragedy

With a great many ties to VT, I have been following the tragic shootings there closely. While my former student (Nakhiah Goulbourne) and my former department head (Dick Benson) are both safe, I am afraid we may have lost one of our own this morning. From an AP report, a student stated that the instructor teaching a 9:05am mechanics class in 204 Norris Hall was killed. According to the timetable of classes at VT, this instructor would have been Liviu Librescu. I certainly hope the AP's report is wrong. As someone very interested in shell theories, I have spoken with Prof. Librescu many times and followed his work. His loss would be a great loss to our community.

The Leonhard Euler Tercentenary

Just a reminder that this Sunday, April 15 will be exactly 300 years since Leonhard Euler was born.

I am sure many mechanicians will toast this weekend on this extraordinnary anniversary to the person who laid down much of the foundations in mathematics and mechanics.

Where are fluid mechanicians?

iMechanica has just passed the milestone of 1000 registered users, and showed no sign of slowing down. Despite all the enthusiasms among a growing number of active users, you might have noticed that iMechanica is missing a powerful community: the community of fluid mechanicians.

Watching my colleagues Howard Stone, Michael Brenner and L. Mahadevan, I find the field of fluid mechanics just as exciting as the field of solid mechanics. The exploration of flow in small devices, as well as in cells and tissues, has just opened new opportunities. There are plenty of other challenges in fluid mechanics at all size scales.

Daniel Bernoulli

Daniel Bernoulli

       Danel Bernoulli, the most successful of all the Bernoulli's was born in Groningen, The Netherlands on 8th February in 1700. His father Johann Bernoulli was working as professor of Mathematics at Groningen then.  Later they moved to Basel, Switzerland which was their native place.

      Daniel did his PhD in Medicine as Johann insisted him to do so. But, as Daniel was ver much interested in mathematics he was learning math while doing medicine. He also worked with another great mathematician Leohnard Euler (who was a student of Johann Bernoulli in Basel) in St. Petersburg.
