meshless methods summer school (Cardiff University, UK)
Dear all,
Cardiff institute of Mechanics and Advanced Materials is organising the first UK Summer School on Meshless Methods in Mechanics on the 29th and 30th of July 2013. The schedule is below.
Assistant Professor Position open at the Division of Computational Mechanics, Ton Duc Thang University, Vietnam
We are opening one or two Assistant Professor positions at the Division of Computational Mechanics, Ton Duc Thang University, Vietnam led by Prof. Hung Nguyen-Xuan and Dr. Trung Nguyen-Thoi. The candidates who hold a PhD degree on Mechanical Engineering, Civil Engineering or Computational Engineering are expected to work on some national projects on the field of computational fluid dynamics (CFD) and enhance the on-going research activities of the group.
Information on the Ton Duc Thang university can be found here
A review on multiscale methods for material modeling
Dear all,
Please find enclosed our paper which is published on Journal of Multiscale Modelling
Vol. 3, No. 4 (2011) 1–42 which gives an overview of state of the art multiscale techniques for material modeling.
The paper discusses the following topics: homogenization, Representative volume element, computational homogenization (Fe2 methods) for both both bulk materials and strong discontinuities.
I hope the paper is useful for beginners to the field.
All the bests,
A free program to generate interface elements in an existing FE mesh
Hello all,
Last year when I started implementing interface elements to model material failure, I realized that the formulation is easy except how to generate a mesh with interface elements. I did a googling to search for such a free program. Amazingly, I did not find any although there are many researchers working on the fracture mechanics field.
So, I wrote a small object-oriented C++ program which reads a FE mesh, duplicates nodes and insert interface elements where asked. The program is able to
Looking for a postdoctoral position in the field of (solid) computational mechanics
Hello,
My name is Nguyen Vinh Phu, a PhD student at Delft University of Technology, the Netherlands. I have been working with Prof. Bert Sluys on a project named "Coarse graining of failure in heterogeneous solids" since July 2007. I am finishing my work and therefore seeking for a postdoctoral position starting after July 2011.
My expertise in computational solid mechanics includes
(1) Finite elements, extended finite elements and meshless methods.
Crack penetration in cohesive zone models
Hi all,
I am conducting some cohesive crack simulations within the framework of XFEM. The cohesive model is an initially rigid traction-separation law for mode I. In order to deal with negative values of the normal sepration/jump, I use a penalty stiffness K.
about the multiscale aggregating method (MAD) of Prof. Belytschko
Hello all
I have spent a large amount of time trying to undertstand the multiscale aggregating method (MAD) of Prof. Belytschko. Unfortunately, I still can not compltely understand the method.
If there is anyone here in the forum already gets clear about the method, please help me.
