Hi all,
I have created a triangular element for abaqus, I did this in Matlab, compiled that to C, compiled that to an object file. When I run a simple script, where I do not use the element, but just say that user=userelement.obj, the system runs without a problem. When I change my input file as follows:
* user element, type=U3, nodes=3, coordinates=2, variables=31
*UEL PROPERTY, ELSET=ALL
1
*Element, type=U3
1, 1, 2, 3
I am trying to simulate creep damage in welded components in ABAQUS. I have four different sections in the same model assigned to four different materials. They are weld metal, base metal and Heat affected zones. I have to write a creep subroutine. For all the zones, creep equation is the same , but the parameters or constants change. i want to know how can I assign different parameters for different materials in the fortran source subroutine? what is the variable used for Material 1 , material 2 etc in standard ABAQUS?

Dear iMechanicians,
I have applied for the job of "Associate Professor" in the Department of Mechanical Engineering at COEP, Pune, India [^]---the same place from where I did my PhD (Mech.) research.
Hello,
I'd like to ask if anybody knows if it is possible to use an ABAQUS usersubroutine that could vary some parameters (τmax, kn or ks etc) of the cohesive zone model of ABAQUS with the vertical pressure applied on the interface. The new ability of ABAQUS to support cohesive behaviour in contact surfaces seems very interesting and useful, however how could somebody simulate the interface under a compression - shear regime that may follow a Mohr-Coulomb type behaviour?
Since my research touches on the basics of QM, I have developed this habit of visiting arXiv.org every now and then. Last week or so, at arXiv.org, I found a couple of interesting articles on physics in general. I would like to share these with you.
A postdoctoral research position in the modeling of failure mechanisms for lithium ion batteries is available immediately at the Richard G. Lugar Center for Renewable Energy in Indiana University-Purdue University Indianapolis (IUPUI). The candidate will work on the study of failure mechanisms of lithium ion batteries which are related to lithium ion diffusion, heat generation and transfer, chemical reaction, and stress development inside the battery.
