SUBMODELLING IN ABAQUS and MASS DIFFUSION ANALYSIS
Do any body working on ABAQUS Submodelling for Mass diffusion analysis.
History of Bueckner’s principle?
I am hoping someone has some historical knowledge of some
interesting mechanics, or just an interest to discuss it. A superposition principle is widely used to solve crack problems, with illustrations like these:

Electric analysis in abaqus
Hi,
I want to do an electro-mechanical analysis in abaqus. The specimen is a steel block of 50 x 50 x 20 mm with a groove/slot of 4 x 25 x 20 mm as shown in attached image.
I want to pass 20 amps current at location shown in red and then check the voltage drop at location shown in blue colour. Please can guide me the how to do this analysis in abaqus.
Thanks

COMSOL with stiffness or constitutive matrix extraction
Hello, all:
Can anyone please help me how to deal with the following problem in COMSOL? Thanks a lot.
How to extract the global stiffness matrix [K] or material constitutive matrix [D_ep] for each load increment after convergence using MATLAB?
Thanks again.
Regards,
Xu
ABAQUS + gfortran (abaqus_v6.env)

Hi
has anyone succeeded in compiling and linking a user define subroutine (e.g. DISP) with gfortran in ABAQUS? I appreciate the issues of linking e.g DISP.obj (compiled with gfortran) with object files precompiled with ABAQUS, however, as long as all compilers are set to target the same platform and architecture, for example i386 instruction set on Linux, then you should be able to link the files. So I feel it is not necessarily a lost cause.
Continuum Modeling of Nonlinear Vibration of Graphene Resonators and Graphene-Based Mass Detection
We have employed continuum elastic model such as plate model for understanding the nonlinear vibration behavior of monolayer graphene and graphene resonator-based mass sensing. This work was published in Nanoscale Research Letters (Vol. 7, Art No. 499, 2012).
