Hi All,
I am analysing a fiber composite solid plate with a large and small holes. The model is meshed with C3D8R elements. The output has U and RF in global CSYS and S, E in local CSYS. I have problem in reading S and E written in local CSYS. I know it is very simple, but I cant able to figure it out. Those who know, how to read the S and E in local CSYS, please help me. Tks in advance for your time and advice.

Hello everyone:
1. I have built a FEM model 2D plane strain using ABAQUS/Standard (CPE4R) elements,
2. I am modeling the contact between a cylinder and a plate in 2D.
3. The Cylinder material is given is ELASTIC ISOTROPIC material with no plasticit E=310 GPa
4. The plate is with a Ramberg-Osgood plasticity with a Young's modulus E=210 GPa.
5. The mesh at the the contact point is VERY refined element characteristic length is about 1 micron. (My model units are (mm,N,sec)).
These days I've been applying oneself to implement the Chaboche viscoplastic model in ABAQUS user-subroutine for simulating the cyclic loading in single crystals.
The procedure can easily get out. I'm not sure about the problem, the deduction of Jacobian, the convergence?
Btw, I know there is free subroutine for crystal plasticity by Huang YG. I wonder if the UMAT routine for chaboche model is available, then I can generalize it to fit for my case.
I am trying to create a model of a travelling wave ultrasonic motor and have found it difficult to find out how to apply the natural frequency of a steel ring to it at two seperate points, seperated by an angle of about 11 degrees. Any ideas or help would be appreciated.
Dear, I use the abaqus present , how can apply a tightening torque between an implant (screw) and the bone with abaqus......... thank you ¶
Please, I need some EFD or CFD software that has an Student Version. I have to make an analysis Solid-Fluid and vice versa, but i have no software to make that.
Now I'm using Pro/E to make Streches and statics analysis, but i cant do any EFD or CFD without any patch or software. Anyone knows any?
Tanks!
I have noticed that a lot of people are using UMAT and VUMAT material model
subroutines for their researches. However, most of these subroutines do not
find their way to free code market and remain in the hands of the developers.
Therefore, a lot of wheel re-inventing has to be done by other people. Since
development and testing of a material subroutine takes a damn long time, I
think it is a good idea if each of us can share the subroutines she has
developed with the others. I know that a couple of subroutines are publicly
