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.

Creating a multi-keyframe animation with d3.js.

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 

Nonlinear programming and closest point return plasticity

New article:  Nonlinear programming and closest point return plasticity http://www.parresianz.com/mechanics/plasticity/algorithm/primal-dual-closest-point-return/

This article tries to justify the use of backward Euler stress updates.

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.

Arc Length Continuation method fails at low arc length values.

I have implemented a Arc length continuation method for material non-linearity. The program quits with low arc length values while it progresses well for high arc length values. I am attaching a png image for your understating  about the nature of the force deformation curve. Can you please clarify me about the problem and provide me any suggestions on it.

Thanks in advance.

Politecnico di Milano creates a large debate in Italy with its decision to teach only in English

Recently, Politecnico di Milano in Italy has attempted to force all teaching at Master level in English.  This has been stopped by some academics who went to different levels of administrative courts, and recently there was a prononciation of the Supreme Court.  The matter is not settled yet, but you can find an account of this with various links here.

What's the difference between Cohesive Zone Model and Joints Element in discrete element method?

Choose a channel featured in the header of iMechanica: 

Hi,

I am a PhD student working on rock mechanics. I have studied Cohesive Method for a few times. But I am confused on What the special functions the Cohesive element have compared with Discrete method? 

For one DEM software UDEC, model is consisted of solid elements and joints elements. What's the difference between Cohesive element and Goodman element?

Harmonic analysis with a crack?

Choose a channel featured in the header of iMechanica: 

Hello everybody,

                          I am trying to perform a harmonic analysis of a material sample (say a simple 2D plate) with an edge crack in it using 'Ansys R16'. I see that under sinusoidal loading condition, the two crack faces open or close and interpenetrate (after closing which is not possible practically).

          1.  I believe, stiffnesses of the crack faces change during interpenetration and so the results are not credible anymore.
