Carlos Felippa CE230A Fall 1963 Class Notes.pdf - course taught by Prof. Pister, started before the assasination of President John F. Kennedy in Nov 1963. Prof. Felippa said “The Notes look nice because I redid the shorthand in the evenings, as a way to understand and absorb the material, which was tough in my first year at UCB. Also to learn English grammar.”

Editor's note: In the above class notes, p.29, the section on constitutive equations started on Oct 18, 1963, as mentioned in Prof. Felippa's tribute. LVQ

Professor Peter Wriggers

During Prof. Wriggers (right in photo) first visit to Berkeley (1983–84), he met with Prof. Pister and Prof. Robert (Bob) Taylor, sometimes at a coffee shop, sometimes in Bob's office, and talked about FEM and university politics.

The above photo was taken in a large “infamous room” 508 with no windows, where graduate students and visiting scholars worked in cubicles, such as the one above. Peter shared the cubicle with the dean of the University of Beirut, Lebanon (middle in photo) and Prof. Dietrich Hartmann of Bochum University, Germany (left in photo). Everyone bundled up with a sweater or a jacket because of the cold air conditioning inside, even though it was warm outside.

Peter returned to Berkeley in 1988, and met Karl in Bob's office, which he used when teaching an advanced FEM course.

Editor's note: Prof. Wriggers has been the Editor-in-Chief of the Computational Mechanics (Internet archived on 2021.09.18) since 2001 (20 years as of 2021). Room 508 in the photo above was in Davis Hall. LVQ

Professor Takewaki met with Professor Pister his then PhD student Joel Conte (now professor at UC San Diego) in 1990, on his first visit to Berkeley for 12 months, to discuss the application of an Auto-Regressive Moving-Average method for earthquake ground motion generation for seismic design of building structures.

Izuru again visited Berkeley for a few days in September, 2017, when he also met with Prof. Pister before giving a seminar to Berkeley CEE graduate students.

“I was visiting UC Berkeley with my wife Helga as a guest and PostDoc of the department of civil and environmental engineering from September 1982 until July 1984. It was a personally wonderful and scientifically very inspiring time particularly due to my hosts Professor Jerome L. Sackman and Professor Robert L. Taylor. Prof. Karl Pister was dean of the college by then providing a great scientific atmosphere as well as a scientist in the field of mechanics and a head of the school. For my own scientific career and professorship at the University of Karlsruhe (nowadays Karlsruhe Institute of Technology) this time was of utmost importance.”

Professor Jiann-Wen (Woody) Ju

Professor Ju received his MS degree from Dean Pister in June 1983 at the Commencement of the College of Engineering at Greek Theater of UC Berkeley. After passing the Ph.D. preliminary exam in early 1984, Woody requested a personal meeting with Prof. Pister and left a meeting note with Prof. Pister's secretary. Woody soon started to pursue his doctoral dissertation under the joint supervision of Prof. Karl Pister and Prof. Robert Taylor from Spring 1984 to Fall 1986. Many years later, Prof. Pister miraculously discovered the hand-written meeting note by Woody on his desk, and mailed the note to Woody at Princeton University. That written note was the beautiful beginning of a lifetime relationship with Prof. Pister and the grand beginning of the academic career of Prof. Ju.

Professor Hans Irschik

“As a student of academic teachers like Heinz Parkus and Franz Ziegler, I made my first scientific experiences in thermal stresses, a field to which I returned since then often. (Inset photo circa 2011.)

Recently, I discussed with Professor Alex Humer on a possible consistent extension of geometrically exact isothermal beam theory to thermoelasticity. We came to the conclusion that the highly valuable representation of the free energy function for isotropic thermoelastic solids was suggested by Lu and Pister, which I did remember from older days, would be an ideal starting point for such a study.

I am deeply grateful that the Special Issue organized by Professor Loc Vu-Quoc and Professor Shaofan Li gave us the opportunity to gain a deeper understanding of this and other important works by Professor Karl S. Pister, to whom we dedicate our paper on the occasion of his 95th birthday in highest appreciation and with our cordial wishes.”

Professor Alexander Humer

In retrospect, the first occasion on which I came across the name of Karl Pister most probably dates back to 2007. In the second half of 2007, I began working on my diploma thesis on the continuum modeling of volumetric growth, for which the review article by Lubarda [1] on multiplicative decompositions in the constitutive modeling of inelastic processes was an important source of information. In the section on thermoelasticity, the review article mentions the paper of Lu and Pister [2], which provides the continuum mechanics foundation of our contribution to this special issue.

Four or five years later, when I was PhD student, I was contacted by one of the reviewers of my article on sliding beam, who approached me asking whether I was interested in a collaboration. This reviewer, who fortunately only requested minor revisions only, turned out as Professor Loc Vu-Quoc, who together with the editor of CMES, Professor Shaofan Li, co-authored the seminal article on the dynamics of sliding beams [33] I was referring to in my paper.

Ever since, I've been lucky to be in regular exchange with Loc. Our weekly meetings became a fixed point in my calendar and our discussions soon extended beyond scientific topics: from linguistics to pianos to politics, to mention only some, Loc and I spent many evenings (me)/mornings (him) on Skype talking about ‘life, the universe and everything’. Loc also allowed me more than a glimpse into private life, which was how I learned that he named his son Karl after his academic teacher. A photo with Loc's family was when I first ‘saw’ Karl Pister.

I remember that, not too long ago, Karl Pister was indirectly involved in Loc's and my discussion, in which we talked about the origins of Austrian church tax, after Loc brought up Pope Francis’ moving article “A Crisis Reveals What Is in Our Hearts” in the New York Times on the American Thanksgiving Day, 26 Nov 2020 (Internet archived on 2021.06.25). Loc said he often went to a cathedral in Paris on Sundays with a Catholic friend to listen to organ music. The Austrian church tax came up when Loc asked whether young Austrians went to church. Karl Pister knew very well about the German church tax (“Kirchensteuer”), and wanted to learn more about the history of the Austrian church tax (contribution, “Kirchenbeitrag”).

Also not too long ago, my teacher, Hans Irschik, in the meantime Professor emeritus, approached me whether I could help him get some article on thermoelasticity, i.e., the paper of Lu and Pister [2], and whether I was interested to work with him on the topic. I gladly agreed to join in given the (social) distance COVID-19 has brought along.

This is how the circle eventually closes: Telling Loc about our work, we were invited to contribute to this special issue.
