Short Course on Mechanics of Foams
A short course on the “Mechanics of Liquid and Solid Foams” will be offered at CISM, the International Centre for Mechanical Sciences in Udine, Italy, 3-7 July 2017 (see brochure attached).
The course will focus on relationships between the cellular microstructure and nonlinear mechanical behavior of liquid and solid foams, and foam-like biological and synthetic materials. Theoretical models, experimental methods, and numerical simulations will be presented. The course is aimed at PhD students, postdocs, and researchers in academia and industry.
The speakers are:
Reading XML files containing gzipped data in C++
Once upon a time, the CEO of my company asked me why I did so much software engineering for my work. My response was that software engineers were unlikely to produce what I needed in the short time frames that I had at my disposal without me spending a huge amount of time training them.

Something that should be in the toolbox of every modern researcher. Static plots in journals are not good enough given today's technology.

Summer School on Computational Materials Science at Texas A&M
On behalf of the Center for intelligent Multifunctional Materials and Structures (CiMMS) and the Department of Materials Science & Engineering at Texas A&M University, we would like to announce the coming, sixth iteration of the Texas A&M Summer School on Computational Materials Science (see attached flyer). The school will take place in College Station, TX from July 23 – Aug. 4. Application deadline is May 1.

Forward vs backward Euler for return algorithms
In Part 5 of my series on return mapping for plane stress plasticity, I claim that the obsession with backward Euler is not justified if accuracy is important. See http://www.parresianz.com/mechanics/plasticity/algorithm/plane-stress-drucker-prager-return-part-5/.
Let me know if you disagree and why.
