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 

Part 7 of the series: Specializing for isotropic elasticity and rank-4 tensor projections http://www.parresianz.com/mechanics/plasticity/algorithm/closest-point-return/

-- Biswajit

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.

-- Biswajit

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.

-- Biswajit

Parts 3 and 4 of the series on plane stress Drucker-Prager plasticity are now online.  More to come soon.

Stability and Bifurcation of Dynamical Systems:
Theoretical Aspects and Applications

July 3-7, 2017, Savona, Italy

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.

This is a reminder that the deadline to apply for the financial aid for the summer course in Udine is approaching:  March 22. 

Short course at Centre International de Sciences Mechanique (CISM), Udine.

May 22-26, 2017

Lecturers:  S Forest, I Groma, D McDowell, S Mesarovic, J-N Roux, H Zbib

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.

When: Tuesday, February 7, 2017

Where: Synopsys Reading Training Centre, 100 Brook Drive, Green Park, Reading, RG2 6UJ, United Kingdom

Overview

This one-day intensive training course intends to give new and existing users sufficient knowledge of the basic functionality of Simpleware software. It will allow you to develop workflows based your areas of research and future projects.
