UEL, ABAQUS input file
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
Creep simulation - welded zones
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?

An Urgent Appeal for Your Support of My Job Application at COEP's Mechanical Engineering Department
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.
Cohesive material zone model and ABAQUS subroutines
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?
In-surface Buckling of Silicon Nanowires on Elastomeric Substrates
Buckling of thin layers or aligned arrays of stiff materials on elastomeric substrates has many important applications, such as stretchable electronics, precision metrology and flexible optoelectronics. These systems show one common phenomenon, the stiff thin layers buckle normal to the substrate surface (out-of-surface buckling). By contrast, we recently reported for the first time that silicon nanowires (SiNWs) on elastomeric substrates buckle only within the substrate surface, i.e. in-surface buckling. Experimental process to obtain buckled SiNWs is described.
Food for Thought: A Few Recent arXiv Papers
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.
