effective properties of laminates
Hi!
Is there any SIMPLE (direct) way to obtain effective properties of laminates in Abaqus?
Thanks in advance.

SIF semi-elliptical crack in pipelines
Dear all,
I am working in my under-graduate thesis. Basically, i'm trying to calculate the SIF and J-Integral for semi-elliptical surface crack using CINT command in ANSYS APDL (all of this in a pipeline model). I have seen one paper shows SIF's distribution along the crack front like the following picture (fig. 8):
In my analysis I have obtained the following distribution (I have used a/c=0.5 with a/tc and tc/Rc equal to the fig. 8):
Microstructurally based cross-slip mechanisms and their effects on dislocation microstructure evolution in fcc crystals
Three newly identified cross-slip mechanisms from atomistic simulations of fcc crystals, namely surface, bulk and intersection cross-slip types, were hierarchically informed into discrete dislocation dynamics simulations. The influence of each cross-slip type on the evolution of the dislocation microstructure in face-centered cubic microcrystals having different crystal sizes and initial dislocation densities was investigated.
Postdoc Positions at Brown University (Solid Mechanics), Providence RI
The solid mechanics program at Brown has two openings for postdoctoral research associates in the areas of computational modeling of battery electrode materials, and computational design of advanced high-strength steels. One position is available immediately; the other towards the end of August. Both projects will have opportunities to work closely with experimental and industrial collaborators.
Problem with user routine (USERELEM) of Ansys
Dear imechanica friends,
I am using userelem in Ansys. When I model a curved shaped structure like a shell, and mesh it in the context of the element ET300, I get error below:
‘unable to mesh area 3 because of shape problems. It may help to change element size on edges of area’
When I use a trick to call ET181 and then mesh, and then change the element type to ET300, the following error is appeared!
‘Negative element Jacobian value 0 at element 10. This is due to wrong element order or bad mesh’

Element set creation by position coordinates
Hello
I'm simulating weld process in abaqus, in which the welding path is circular.For modeling the process I use model change (Deactive and activation of the element).For this I need to locate the element by location in my script. Is there any command that can do this?
Thanks
Smeared Crack and Cohesive zone modeling of concrete in ABAQUS
Can anybody help me in using smeared crack and cohesive zone modeling in concrete for different grades. I was actually facing problem in using the same to identify fracture parameters of concrete using ABAQUS. I will also be helpful if anyone let me know about an alternate method to find fracture parameters of concrete using ABAQUS apart from using models. Thanks in advance.......
