An introduction to metamaterials and waves in composites
My book on metamaterials, "An introduction to metamaterials and waves in composites" has been published on June 16, 2011 by CRC Press (Taylor and Francis).
The book is meant for students, researchers, engineers, and educators who want to get a basic grounding on the theory that is the basis of recent excitement about negative materials, cloaking, transformation optics/acoustics and other wave phenomena in composites.
Reliability and engineering mechanics
The word "failure" can mean different things to different people. Over the past couple of years, my interactions with various groups from industry has shown me that for some people failure means catastropic fracture/buckling while for others it can mean highly localized plastic yielding. Even for relatively simple sandwich composite structures, there is no clearly agreed upon definition of the word.
UMAT code for crystal plasticity
Dear all,
I would like to ask you something about prof.
Huang's subroutine. I want to verify the code, by using published
stress-strain data. But when I am plotting my stress -strain curve I am
always getting a straight line instead of a curve that shows the hardening effect. What could be a reason for this problem?
Regards,
Panos
p.s. I am using a single crystal, single element, and only modify the crystal orientation

Internship in Computational Mechanics (plasticity)
Dear Members,
Hope you will be fine.
I am student in MSc Computational Mechanics, here in Nantes France. I am looking for an internship which is compulsory part of master degree. I am interested in materials, processing/modeling and simulation. I would be grateful for your guidance and help.
Thanks and Regards,

Extended Deadline: XFEM2011 ECCOMAS Thematic Conference on Partition of Unity Enrichment and Applications Cardiff, Wales, UK
Dear colleagues,
The deadline for the registration and submission of one page abstracts has been extended to the 21st February 2011.
XFEM 2011 is one of the successful series of
ECCOMAS thematic events.
XFEM 2011 is a medium-size conference
with a balanced participation covering both the theoretical aspects of the subject and engineering applications.

electrical-thermal modeling in ANSYS
I’m modeling a resistance spot welding process in ANSYS. as you know in this tpic we are dealing with contact elements. in welding step I’ve defined ECC & TCC for contact elements and also have updated geometry from squeezing step and cleared loads, however I’venot been able to achive temrature distribution. I use from plane67 element for a electrical-thermal analysis.
Behaviour of Interface element in delamination analysis
Good morning,
I'm trying to simulate delamination with interface element, with a traction-jump law.
In order to see the Behaviour of the Interface element before the delamination occur, i introduce one interface element (8 nodes ) between two normal linear elastic solid element (quader with 8 nodes also).
I think the strain in the interface corresponds to the Jump
I have many difficulties:
