Dear Colleague: Please consider submitting your nanomechanics related abstract to Symposium 4-1 ("Nanomechanics: Beyond Modulus and Hardness") of the 47th Annual Technical Meeting of Society of Engineering Science, which takes place October 4-6, 2010 at Iowa State University, Ames, IA. The deadline for abstract submission is 5:00pm CST, Monday, June 7, 2010. The meeting's homepage can be found at www.ucs.iastate.edu/mnet/ses2010/home.html.
How to use ALE in modelling extrusion of AL circular tubes through hollow dies(porthole)
Hello,I am an MS student working on extrusion of AL tubes through hollow dies using ABAQUS.I am facing problems in the ALE settings. The job aborts due extensive distortion even after applying and increasing the number of remeshing frequency and sweeps. I greatly appriciate if any one could help me out.
Research Position Opening on Energy Harvesting
Applicants are invited for an immediate opening of a postdoctoral
researcher position at Northwestern University. This researcher will work on
a research project on vibration energy harvesting that involves close
collaborations with experimentalist. Candidates should possess an earned
Ph.D. in Mechanical Engineering, Physical sciences, Electrical Engineering,
Material Science, or related disciplines. Candidate should have a strong
theoretical background in solid mechanics and previous experience in solving
Writing User Routine in DEFORM 3D
Hi all,
I am new to DEFORM 3D and I am intended to simulate the effect of coolant pressure on the chip formation in metal cutting.
I dont know how to incorporate the mechanical effect of coolant pressure on chip formation in machining.
Are there any standard options in DEFORM 3D, which I can use to simulate the same?.
If not, will writing a user subroutine in DEFORM help me to simulate the same?. If the user subroutine, is the only way to do so, I would like to get some material on writing user subroutine in DEFORM 3D?.
Why different between Solid5 and C3D8?
Has anyone compared the results of Ansys solid5 element and Abaqus c3d8 element? I tried a very simple example with
exactly same conditions for both elements but got very different displacement results. I put both input files here,
can anyone help me check whether there is something wrong? Thanks.
Ansys Input:

JWL and Lee Traver EOS for RDX
Hi !!! all
I really struglling to get the JWL and Lee Traver EOS parameters for RDX .
If anybody can help seriously I will be highly obliged. Atlest the EOS
parameters of Comp-A5 or PBX 9604 having higher percentage of RDX (98.5
% and 96% respectively) will be sufficient.
Flexible Linear Shaped Charge Modeling
Hi !!! all
I am doing the Hydrocode simulation using AUTODYN 2D Explicit Hydrodynamic Code. There is apoint of doubt in simulation of a 2D problem regarding the location of Detonation inside the explosive. In the case of a conical shaped charge it is very easy to assume the detonation at the apex of the cone but in case of FLSC being a linear cord and the initiation is done axially, it is very difficult to assume the same condition as that of conical shaped charge.
Please give me some useful solution.
