SIF in ANSYS
To calculate stress intensity factor ANSYS have two option:
1. Plane stress
2. Plane Strain
In a completely 3D problem, How can I use ANSYS to calculate stress intensity factor with out using J integral?
Need tutorials and macros related to piezoelectricity using ANSYS
Hi,
I recently started working with piezoelectricity using ANSYS. Can anybody suggest me some tutorials and macros for ANSYS-piezoelectricity.

Artificially High Read Counts
There has been some discussion about the low ratio of replies to reads on iMechanica. While it's nice to think that a lot of people are reading our posts, I wonder how many of those 'reads' are really bots indexing the page. For example, I posted a blog entry last night around 11:00 and nine hours later it says it has been read 45 times. A couple of those can be attributed to me but I'm sure 40 real people have not read the post. Add to this the fact that the post is already showing up in Google.

Effects of grain boundary adhesion and grain size on ductility of thin metal films on polymer substrates
We study the effects of grain boundary adhesion and grain size on the ductility of thin metal films well bonded to polymer substrates, using finite element method. It is shown that the ductility of polymer-supported metal films increases approximately linearly as the grain boundary adhesion increases, and as the grain size decreases. A rule-of-thumb estimate of the ductility of polymer-supported metal films agrees well with the simulation results.

Viscoelastic prarameters setting in ABAQUs
i'm try to do a dynamic analysis by abaqus and i faced some problems.any help is appreciated.
The structure is a 3 layers plates,a viscoelastic material sandwich between 2 steels.i modeled the 2 steel as sheel 'S8R"and the rubber as contiuum "c3d20r",rubber is not thin. Now i don't know how to set the parameters requried by the Code.I hove some parameters abuout the viscoelastic material.,includeing shear storage modulus G(f)=exp(-2.69292)*f^(0.6937),and loss factor of the material L(f)=exp(0.60503)*f^(-0.08807), Possion ratio=0.49, where f is frequency in Hz.
Unconverged Mohr-Coulomb Plasticity, ABAQUS
Dear Abaqus Users,First of all, I want to clarify that I am a beginner in Abaqus (only few months) and new in iMechanica. I have been modeling an excavation in Abaqus/CAE. I am using several layers of soils which have been modeled using Mohr-Coulomb model, the wall as an elastic material. Both the wall and the soils were modeled with 2D solid elements (plane strain).I have been facing with lots of problem with the interaction of the first layer and the wall, "UNCONVERGED MOHR-COULOMB PLASTICITY" in the GEOSTATIC STEP!!!!.
