The following description is for a position is in my research group at Khalifa University in Abu Dhabi, United Arab Emirates. 

Hi

I am trying to model interface crack propagation in Abaqus using Cohesive Interaction (default module in Abaqus). My model consists of two rectangular domains attached to each other by the longer edge. I am defining two surfaces on each of these domains and defining traction separation laws for these surfaces. There is a small portion in the middle for which I am not defining any traction separation law (thereby making it my notch). I am then applying displacement controlled loading on the remaining two longer edges. I am having two set of problems:

Hello Eeveryone,

I am working with Pore-pressure cohesive element in abaqus. In this element, I can define laminar fluid flow. However, I was wondering to see if I can change it to turbulent flow?

In these types of elements we use Poiseuille's law to model fluid flow. So the form of it is (qd=K_t*del_p). Is it possible to change this equation to another equation with the same degree of freedom?

Thanks,

In this paper we describe the dynamic behavior of elongated multi-structured media excited by flexural harmonic waves. We examine periodic structures consisting of continuous beams and discrete resonators disposed in various arrangements. The transfer matrix approach and Bloch-Floquet conditions are implemented for the determination of different propagation and non-propagation regimes.

Good day

I have numerous errors when assigning the FRIC subroutine to .INP file. Any suggestions would truly be appreciated.

What I did:

Within my subroutine I change the .VAL=PROPS(X) to a designated number—i.e. .VAL=0.00

ABAQUS doesn’t recognize these variables(PROPS(X)) sometime.

I created the LIB files (abaqus make library=XXX.for) needed when running the interactive job.

Then added the .lib to the abaqus environment (abaqus_v6), then, allocated the .for file to the working directory as well as the .inp file.

Hello,

I have written a UEL in C, with several functions, for a geometrically nonlinear problem. It's said in ABAQUS documentation that UEL's can be written in C, but I haven't been able to find much information about how to run those UEL's. I'm using ABAQUS 6.13 on Win7. Any help on that would be greatly appreciated.

Thanks,

Hello,

Does anybody have any experience linking ABAQUS with gfortran and gcc, and then compiling user subroutines with them?

Thanks,
